Amazon Elastic Container Service (ECS) is a fully managed container orchestration service that enables users to easily run, manage and scale containers on AWS. With ECS, you can deploy containers either on a cluster of Amazon EC2 instances or on AWS Fargate, a serverless computing engine for containers. In this article, we’ll take a closer look at what ECS is and how it works, including the different components and launch types available.

In this article, we’ll take a closer look at what ECS is and how it works, including the different components and launch types available. We'll also briefly compare the features of EC2 and Fargate, and explore the use cases for each launch type. By the end of this article, you'll have a better understanding of how to use ECS and be able to make an informed decision on which launch type is best for your needs.

But first, let's define what ECS is. ECS is a highly scalable and powerful tool for orchestrating containers that are run on Docker. It allows you to deploy containers from your local environment via Docker and provision access to those containers from anywhere, resulting in zero downtime and no complicated configurations. With ECS, you can scale numerous containers with just a single click.

ECS provides the underlying infrastructure to create task definitions for your tasks and services; however, you still have to select a launch type that will handle running, stopping, and deploying your tasks and services.

CreateContext
Tags: webdev, react, programming, beginners
Published: 2023-01-18 02:35:45

Developers can construct a context object to use to transport data across a component tree using the CreateContext method supplied by the React library in JavaScript, eliminating the need to manually pass props down at each level. Data sharing across components that are not directly connected in the component tree is made possible by this.
Here's an example of how to create a context object:



![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/33hyrmrsck3df8l97myh.png)
The createContext method takes an optional default value as its argument, which will be used as the initial value for the context if a Provider is not present further up the component tree.

Once the context is created, it can be consumed by any component in the tree using the useContext hook or the Context.Consumer component.

Here's an example of how to use the context in a component:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fuctyk9nzo5v9co8bqg6.png)


The Context.Consumer component is a part of the React library. It is used to access the context data that has been provided by a Context.Provider component. The Context.Consumer component takes a single function as its child, which is called with the current context value. The function should return a React element, which will be rendered with the current context data.

For example, in the following code snippet, the ThemeContext.Consumer component is used to access the theme value provided by the ThemeContext.Provider component. The function passed as a child to the ThemeContext.Consumer component is called with the current theme value, and the returned element is rendered with the current theme.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bgn6p2uajggbn15vdgqx.png)

To provide the context with a value, you can use the Context.Provider component.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vq2v7eef8o09ezecr5tw.png)

In this example, the context value for  MyComponent component will be "Hello World." The context will also be used by any components lower down the tree that consume it. It is important to remember that you can use the context's Provider anywhere in the component tree, it doesn't need to be the parent of the component that uses the context.

You could also update the context value by using the state and setState Hooks

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5zlab7n51ns89uvapzwa.png)

In this example, the value of the context will change to "New Value" when the button is clicked and all the components that are consuming the context will receive the new value.

To sum up, createContext is a powerful tool that allows data to be shared between components that are not directly connected in the component tree, it can be consumed with useContext or Context.Consumer and provided with Context.Provider and it allows the context value to be updated with state and setState hooks.
Core Java - Access Modifiers
Tags: java
Published: 2023-01-18 02:15:15

Java provides various access modifiers to variable method and constructor. 

private   package  public  protected
If we don't use any of these it will be package by default.
A class can be public or package not private or protected because no other class can access the class.

Access modifiers can't be used against block.

React State Management: When to Use useState and useReducer Hooks
Tags: webdev, javascript, hooks
Published: 2023-01-18 02:12:51

React Hooks are a powerful tool that allows developers to manage state and side effects in functional components. Two of the most commonly used hooks are `useState ` and `useReducer`. Both hooks allow you to manage state in your components, but they are used in different situations and provide different functionality.

`useState `is the most basic hook for managing state in a React component. It allows you to set and update a single piece of state. The hook takes in an initial value and returns an array with two elements: the current state and a function to update the state.

```js
const [count, setCount] = useState(0);
```
In this example, count is the current state and setCount is the function to update the state. To update the state, you simply call the setCount function and pass in the new value.

```js
setCount(count + 1);
```
`useState `is great for simple state management, such as keeping track of a form input or a toggle button. But it can become cumbersome when managing more complex state.

`useReducer `is a more powerful hook for managing state in a React component. It allows you to manage complex state and handle multiple actions in a single function. The hook takes in a reducer function and an initial state, and returns an array with two elements: the current state and a dispatch function.


```js
const [state, dispatch] = useReducer(reducer, initialState);
```
The reducer function takes in the current state and an action, and returns the new state. The dispatch function is used to trigger the reducer function and update the state.

```js
function reducer(state, action) {
  switch(action.type) {
    case 'increment':
      return { ...state, count: state.count + 1 };
    case 'decrement':
      return { ...state, count: state.count - 1 };
    default:
      return state;
  }
}

dispatch({ type: 'increment' });
```
In this example, the reducer function is handling two different actions: 'increment' and 'decrement'. The dispatch function is used to trigger the appropriate action and update the state.

`useReducer `is useful for managing complex state and handling multiple actions in a single function. It allows you to centralize your state management and keep your components simple.

In conclusion, `useState `and `useReducer `are both React Hooks used for managing state in functional components. `useState` is used for simple state management and allows you to set and update a single piece of state, while `useReducer `is used for complex state management and allows you to handle multiple actions in a single function. The choice between the two hooks depends on the complexity of your state and the number of actions you need to handle.
Core Java - Flow Control

Flow control it will manage how the program flow has to go.

selection statements - if-else, switch
Iterative - while, do while, for, for-each.
Transfer statements - break, continue, return, try-catch-finally and assert.

If-else :
   ` if(conditional expressions){
        code to be executed;
    } else{
        code to be executed;
    }`

Nested If:
`if(condition){
code to be executed;
}else if(condtion){
code to be executed;
}else{
code to be executed;
}`

**Switch Statements**
`switch(x)
  {
     case1:
       Action1;
       break;
     case2:
       Action2;
       break;
     default:
       Default Action;
 }`

**While**
`while(condition){
Body of the loop;
}`
it will execute till the condition is false.

**Do while**
it will execute first and then check for the condition.
`do{
execute the condition;
}while(condition);`


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pd63gge3lnkqda0qink8.png)


**For loop**
is a looping statement if we know the number of iterations.
`for(initialization;condition; increment or decrement){
loop body;
}`

Is Rust a good choice for your next web application?
Tags: webdev, programming, rust
Published: 2023-01-18 01:07:16

[Rust](https://www.rust-lang.org/) is a relatively new programming language that has been gaining popularity in recent years. Known for its focus on safety and performance, I think Rust is a great choice for developing web applications, especially for developing server-side applications. In this post, we will see if Rust is a good choice for your next web application and how it can help us create more reliable and efficient web applications.

As you might know, **Rust is known for its focus on safety and performance**. The language has a built-in memory safety system that prevents common programming errors, such as null pointer dereferences and buffer overflows. These kinds of features built in the language itself can ensure that the application will be free from common security vulnerabilities. We can easily catch bugs during development and compilation time.

**Rust is also known for its performance**. The language is designed to be fast and efficient, making it a great choice for server-side applications that need to handle a large number of requests. Rust's performance is also on par with other web development languages like Go.

In addition to its focus on safety and performance, **Rust also has a growing ecosystem of libraries and frameworks** that make it easy to develop web applications. For example, the Rocket web framework is a popular choice for developing web applications with Rust. It is designed to be simple, fast, and secure, making it a great choice for developers who want to get started with Rust.
[https://rocket.rs/](https://rocket.rs/)

Rust is also becoming more popular among web developers. The language is gaining popularity in the web development community, and it is becoming more widely adopted by companies. This is due to its focus on safety and performance, as well as its growing ecosystem of libraries and frameworks.

[A curated list of languages and frameworks built in Rust](https://github.com/awesome-rust-com/awesome-rust)

All of these factors make Rust a great choice for web development and the community is growing as well. Rust is becoming more widely adopted by companies and used in many commercial applications such as Dropbox and Figma.

Javascript Spread and Rest Operator syntax explained...
Published: 2023-01-18 00:39:21

**In this tutorial, we will learn about JavaScript spread and rest operator with the help of detailed examples**

The spread operator in JavaScript allows an iterable (such as an array or string) to be expanded in places where zero or more arguments (for function calls) or elements (for array literals) are expected. It is represented by three dots (...).

Spread syntax looks exactly like rest syntax. In a way, spread syntax is the opposite of rest syntax. Spread syntax "expands" an array into its elements, while rest syntax collects multiple elements and "condenses" them into a single element.

```
let arr1 = [1, 2, 3];
let arr2 = [...arr1, 4, 5, 6];
console.log(arr2); // [1, 2, 3, 4, 5, 6]

```
You can also use the spread operator to spread the elements of an array into a function call:

```
let arr = [1, 2, 3];
console.log(Math.max(...arr)); // 3

```let [first, second, ...rest] = [1, 2, 3, 4, 5];
console.log(first); // 1
console.log(second); // 2
console.log(rest); // [3, 4, 5]

The rest operator is similar to the spread operator, but it is used to capture the remaining elements of an array. It is represented by three dots (...) and is usually used in conjunction with destructuring assignment.

For example, you can use the rest operator to capture the remaining elements of an array into a new one:

```
let [first, second, ...rest] = [1, 2, 3, 4, 5];
console.log(first); // 1
console.log(second); // 2
console.log(rest); // [3, 4, 5]

```

You can also use the rest operator to capture the remaining elements of an array into a function argument:

```
function print(first, second, ...rest) {
    console.log(first);
    console.log(second);
    console.log(rest);
}

print(1, 2, 3, 4, 5); //1
2
[3,4,5]

```
further usage of spread operator with function:

```
const add = function (...numbers) {
let sum = 0;
for( let i = 0; i < numbers.length; i++ ) sum += numbers[i];
console.log(sum); 
};
add()3,2,5)
add(3, 4, 1, 4, 6, 7, 5, 2)
add(9, 2, 1, 4)

```
Hope you have a better understanding of the spread and rest operator after this explanation.
