New Feature in ECMAScript 2024 - New Regular Expression Flag /v (.unicodeSets) 👨‍🎨
Tags: webdev, javascript, programming, es15
Published: 2024-07-06 07:40:49

JavaScript’s regular expression capabilities have just received a powerful upgrade with the introduction of the `/v` flag, also known as .unicodeSets. This new flag enables more advanced and flexible pattern matching with Unicode properties, string literals in character classes, and set operations. Let's dive into what `/v` brings to the table and explore some practical examples.

#### Unicode String Properties
With the `/v` flag, you can now use Unicode string properties to match more complex characters. For instance, the character 🧑‍💻 consists of three code points, making it challenging to match with traditional Unicode code point properties.

Example:

```javascript
//Previously, using the Unicode code point property Emoji via /u
console.log(/^\p{Emoji}$/u.test('🧑‍💻'));  //false

//Now, with the Unicode string property RGI_Emoji via /v
console.log(/^\p{RGI_Emoji}$/v.test('🧑‍💻')); //true

```

#### String Literals in Character Classes
The /v flag allows string literals to be used within character classes using the \q{} escape sequence. This makes it easier to match specific sequences directly.

Examples:

```javascript
//Matching the string literal 🧑‍💻
console.log(/^[\q{🧑‍💻}]$/v.test('🧑‍💻')); // true

//Matching the string literal "abc" or "def"
console.log(/^[\q{abc|def}]$/v.test('abc')); //true
```

#### Set Operations for Character Classes
Set operations within character classes are now possible with `/v`, allowing for more complex matching patterns.

Examples:

```javascript
//Excluding specific characters
console.log(/^[\w--[a-g]]$/v.test('a')); // false

//Excluding specific digits
console.log(/^[\p{Number}--[0-9]]$/v.test('٣')); // true

//Excluding a specific emoji
console.log(/^[\p{RGI_Emoji}--\q{🧑‍💻}]$/v.test('🧑‍💻')); // false

```

#### Improved Matching with `/i` and Negated Unicode Property Escapes
The `/v` flag also improves matching when using the `/i` flag and negated Unicode property escapes.

#### Conclusion
The introduction of the `/v` (.unicodeSets) flag in JavaScript’s regular expressions marks a significant improvement in handling Unicode characters, string literals, and set operations. Whether you're dealing with complex emoji sequences or need more precise pattern matching, /v opens up new possibilities.

Leetcode Day 5: Valid Parentheses Explained
Tags: python, leetcode, beginners, codenewbie
Published: 2024-07-06 07:39:28

The problem is as follows:
Given a string s containing just the characters `'('`, `')'`, `'{'`, `'}'`, `'['` and `']'`, determine if the input string is valid.

An input string is valid if:

Open brackets must be closed by the same type of brackets.
Open brackets must be closed in the correct order.
Every close bracket has a corresponding open bracket of the same type.

Here is how I solved it:
This is a good example on when to use a stack data structure. We are going to use a stack to keep track of the open brackets and ensure they are closed correctly and in the right order. Let's first figure out what is a stack. Look at this image:

![Demonstration of a stack data structure](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xzurkuh0u4os10wsg4zi.png)

A stack is a Last-In-First-Out (LIFO) data structure, meaning the last element added (pushed) to the stack is the first one to be removed (popped). This makes it ideal for matching parentheses, as we need to ensure that the most recent open bracket is closed by the corresponding close bracket.

Let's step through the logic. 

```
class Solution:
    def isValid(self, s: str) -> bool:
        // my solution here
```
- Create an empty stack to keep track of open brackets.
- Create a dictionary to map each type of open bracket to its corresponding close bracket.

```
stack = []
mapping_parentheses = {"(" : ")", "[" : "]", "{" : "}"}
```
-  Loop through each character in the string `s`. 
- If the character is an open bracket (i.e., it is a key in the mapping_parentheses dictionary), "push" it onto the stack.

- Else if the character is a close bracket, check two conditions:

1. `not stack`: If the stack is empty, it means there is no corresponding open bracket for the close bracket, so return False.
2. `char != mapping_parentheses[stack.pop()]`: Pop the top element from the stack and check if the popped element matches the current close bracket using the dictionary. If not, return False.
```
for char in s: 
    if char in mapping_parentheses: 
        stack.append(char)
    elif not stack or char != mapping_parentheses[stack.pop()]:
        return False
```
- After processing all characters, if the stack is empty, it means all open brackets were correctly matched and closed. If the stack is not empty, it means there are unmatched open brackets, so return False.

```
return not stack
```

Here is the completed solution:

```
class Solution:
    def isValid(self, s: str) -> bool:
        stack = []
        mapping_parentheses = {"(" : ")", "[" : "]", "{" : "}"}

        for char in s: 
            if char in mapping_parentheses: 
                stack.append(char)
            elif not stack or char != mapping_parentheses[stack.pop()]:
                return False
        return not stack
```

Exciting New Features in ECMAScript 2024 - groupBy() 🎗️
Tags: javascript, webdev, programming, es15
Published: 2024-07-06 07:39:14

The latest version of JavaScript, ECMAScript 2024, became an official standard on June 26, 2024, thanks to the 127th ECMA General Assembly.

It has included six new features 

- _Grouping synchronous iterable_
- _Promise.withResolvers()_
- _Regular expression flag /v_
- _New features for ArrayBuffers and SharedArrayBuffers_
- _Ensuring that strings are well-formed_
- _Atomics.waitAsync()_

### Grouping synchronously iterable
**groupBy()** : `Object.groupBy()` `Map.groupBy()`
The `Object.groupBy()` method takes an object and a callback function. It groups the object's elements into a new object based on the strings returned by the callback function for each element. The original object remains unchanged.

```javascript
const stationary=[
  {name:'Pencil',qty:100},
  {name:'Pen',qty:50},
  {name:'Rubber',qty:300},
  {name:'Notebook',qty:150},
  {name:'Scale',qty:0},
  {name:'Color Pencil',qty:0},
]
function callbackFun({qty}){
  return qty>0?'available':'notAvailable'
}
const result=Object.groupBy(stationary,callbackFun);
console.log(result);

//output
/*
{
  available: [
    { name: 'Pencil', qty: 100 },
    { name: 'Pen', qty: 50 },
    { name: 'Rubber', qty: 300 },
    { name: 'Notebook', qty: 150 }
  ],
  notAvailable: [
    { name: 'Scale', qty: 0 },
    { name: 'Color Pencil', qty: 0 }
  ]
}
*/
```
The `Map.groupBy()` method groups elements from an object based on strings returned by a callback function. It creates a new Map object with these groups, leaving the original object unchanged.

```javascript
//...
const result=Map.groupBy(stationary,callbackFun);
console.log(result);

//output
/*
Map(2) {
  'available' => [
    { name: 'Pencil', qty: 100 },
    { name: 'Pen', qty: 50 },
    { name: 'Rubber', qty: 300 },
    { name: 'Notebook', qty: 150 }
  ],
  'notAvailable' => [
    { name: 'Scale', qty: 0 },
    { name: 'Color Pencil', qty: 0 }
  ]
}
*/
```

 Functional Testing:
        It focuses on testing the functionality of the software or 
 system.
        Verifies whether the software meets the functional requirements.
        It involves testing the features and functionalities of the 
software, such as input/output, error handling, and user 
interface.
        Tests are typically conducted using test cases or scenarios 
that validate the functional requirements.
        It can be performed manually or using automated testing tools.
        It was done after unit testing and integration testing and 
        before system testing.
Non-Functional Testing:
       It focuses on testing the system's or software's non-functional components.
      Checks to see if the software satisfies the non-functional requirements, including performance, security, usability, reliability, and compatibility.
      It involves putting the software's quality characteristics, including response time, scalability, availability, and maintainability, to the test.
      Several testing methods, including load testing, stress testing, security testing, and usability testing, are used.
      Specialist testing techniques and frameworks are frequently needed to measure and assess non-functional requirements.
      Many development lifecycle stages, including design, deployment and maintenance, can be completed.
Functional testing:                                              
             focuses on whether the software or system works as intended, i.e., whether it meets the functional requirements.          
             It involves testing the features and functionalities of the software, such as input/output, error handling, and user interface.

For example:                                                          
          if you are testing a calculator app, you would check whether it can perform basic arithmetic operations like addition, subtraction, multiplication, and division correctly.                               
          You would also check if the user interface is user-friendly, the buttons are working correctly, and the app is responsive to user input.
Non-functional testing:                                               
             on the other hand, is focused on testing the non-functional aspects of the software, such as performance, security, usability, reliability, and compatibility.                           
             Non-functional testing helps to ensure that the software meets the quality standards and performs well under different conditions.

For example:                                                          
              if you are testing a website, you would check whether it can handle many concurrent users without slowing down or crashing.       
              You would also check whether the website is secure from potential cyber threats like hackers or viruses.             
             Additionally, you would check whether the website is accessible and easy for people with disabilities.
