Am I still a backend developer?

That's the question I ask myself sometimes. Because I always felt like I don't do much. But guess what, I'm still growing. I could remember when I was building an API using the Djangorestframework some months ago, I couldn't figure it out but my goal isn't to only built the API in the Restful state alone but also include the Graphql version of it. I started, read alot online about it, watched videos and after, I built it.

Moving on to the graphql version, I couldn't find suitable resources that covers all I'm searching for. So I decided to build it regardless of how much errors I get and guess what I did it.

Something I want you to know is, as a beginner or intermediate, stop watching tutorials or buying courses, just keep building again and again.
Also, don't measure your level with what you know, but with what you've build for yourself without following tutorials.

Lastly, I'm so happy to get to join hng cohort 11 which is going on right now, if you'll like to join, here is the link [hng internship](https://hng.tech/premium). It's part of what I have been looking forward to.  They also have a premium package for the internship, you can check it here [hng premium](https://hng.tech/premium)

It's a program you don't want to miss if you're trying to master your skill. They have a range of skills you can join.

Hello Dev community!

I'm thrilled to share that I'm beginning my journey as a software engineer, and I couldn't be more excited about what lies ahead. Having recently graduated with a degree in Computer Science, I've eagerly awaited this moment to dive deep into the world of coding, problem-solving, and innovation.


So here's to new beginnings, continuous learning, and making a mark in the ever-evolving world of software engineering. Let's code, create, and innovate together.
Shuffle The Array
Published: 2024-06-27 02:24:33

Today's problem is fairly straightforward. It can be solved with a simple for loop and the `push ` method. 

Given the array `nums` consisting of `2n` elements in form `[x1,x2,...,xn,y1,y2,...,yn]`. we need to rearrange the array into `` [x1,y1,x2,y2,...,xn,yn]`


### Function  Signature
```
@param {number[]} nums
@param {number} n
@return {number[]}
```


### Examples

**Example 1:**

**Input:** nums = [2,5,1,3,4,7], n = 3
**Output:** [2,3,5,4,1,7] 
**Explanation:** Since x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 then the answer is [2,3,5,4,1,7].

**Example 2:**

**Input:** nums = [1,2,3,4,4,3,2,1], n = 4
**Output:** [1,4,2,3,3,2,4,1]

**Example 3:**

**Input:** nums = [1,1,2,2], n = 2
**Output:** [1,2,1,2]

The first thing to understand is that `2n elements` means the total number of elements in the array is twice the value of `n`. The first half of the array consists of elements `[x1, x2, ..., xn]` and the second half consists of elements `[y1, y2, ..., yn]`.

The task is to rearrange the array into `[x1, y1, x2, y2, ..., xn, yn]`.

## Example Breakdown

**Input:** `nums = [2, 5, 1, 3, 4, 7]`, `n = 3`

Here, `nums` has 6 elements (2 * 3 = 6).

- The first half `[x1, x2, x3]` is `[2, 5, 1]`
- The second half `[y1, y2, y3]` is `[3, 4, 7]`

We need to combine them like this:

- Take `x1` (which is `2`) and `y1` (which is `3`)
- Take `x2` (which is `5`) and `y2` (which is `4`)
- Take `x3` (which is `1`) and `y3` (which is `7`)

Resulting in `[2, 3, 5, 4, 1, 7]`.



## Dive into the code

So how do we approach this with code. Let's create a plan:

1. Create a function `shuffle`.
2. The function takes two parameters: `nums` and `n`.
3. Create an empty array to store the result.
4. Loop through the first `n` elements of the array.
5.  Push the current element and the corresponding element from the second half into the result array.
6. Return the result array.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/49mymyxci45nqfb127p8.png)

Conclusion
Today's problem was a great example of how we can use simple loops and basic array operations to solve a seemingly task. 

To recap:

We identified that the array nums consists of 2n elements, split into two halves.
Our goal was to get two halves into a new array in the specified format.
Using a simple for loop and the push method, we created a solution that is both intuitive and effective.

I encourage you to try this problem on your own and see how you can further optimize or modify the solution.

Happy Coding!
typescript and styling issues in react native using native wind
Tags: typescript, reactnative, native, wind
Published: 2024-06-28 21:09:21


In a recent project using React Native, I encountered several challenges related to TypeScript configuration and styling with nativewind. Here’s a summary of the issues faced and how they were successfully resolved:

## Problem Statement:
_**
During development, TypeScript compiler errors (1259, 17004) surfaced due to improper module imports and JSX configuration issues. Additionally, styling React Native components using className with nativewind wasn’t functioning as expected.

**Root Causes Identified:**

_- Module Import Challenges:_

TypeScript errors (1259) pointed out issues with module imports (@types/react) not being compatible with TypeScript’s default module resolution, requiring the esModuleInterop flag to be enabled.

_**

- JSX Configuration:
**_
Errors (17004) highlighted JSX parsing problems because the --jsx flag was missing in the TypeScript configuration (tsconfig.json), crucial for correctly interpreting JSX syntax in React Native.
**_

- Dependency Management and Setup:
_**

Challenges with ExpoMetroConfig.loadAsync and missing expo/tsconfig.base indicated potential version mismatches or incomplete installations of essential Expo-related packages (expo, expo-router, jest-expo).
**Steps Taken for Resolution:**

**_

1. TypeScript Configuration Adjustment:

Updated tsconfig.json to include esModuleInterop: true for seamless module interoperability and set jsx: "react-native" to enable proper JSX parsing for React Native components.


2. Dependency Updates and Installations:


- Ensured all dependencies (expo, expo-router, jest-expo) were updated to their latest versions to resolve specific function errors (ExpoMetroConfig.loadAsync) and ensure compatibility.


3. Project Setup and Execution:


- Conducted thorough cleaning of npm cache, followed by reinstalling dependencies (npm install) to ensure a fresh and accurate setup, including expo@latest for comprehensive updates.
**_

4. Babel Configuration Verification:


- Checked and updated babel.config.js to incorporate essential plugins (babel-plugin-macros) necessary for proper functionality within the Expo project environment.


5. Tailwind CSS Integration (Optional):
_**

- Provided an example and configured tailwind.config.js to integrate Tailwind CSS utility classes (className) seamlessly with React Native components using nativewind.

**_Conclusion:_**


By addressing TypeScript configuration intricacies, ensuring correct dependency management, and optimizing project setup for compatibility and functionality, the project successfully overcame initial challenges. This approach not only resolved technical hurdles but also enhanced development efficiency and maintained project integrity.

This experience underscores the importance of meticulous configuration and dependency management in React Native projects, ensuring smooth integration of tools like nativewind for effective styling and development practices.

A Technical Article about front-end technologies.
Published: 2024-06-28 20:14:45

Introduction

In the ever-evolving landscape of web development, frontend technologies have seen a dramatic transformation over the past few decades. From the static web pages of the early internet to the dynamic, interactive, and highly responsive applications we use today, frontend technologies have played a crucial role in shaping user experiences. This article takes you through the journey of frontend technologies, highlighting key milestones and the modern tools that are driving innovation in the field.

#### The Early Days: HTML, CSS, and JavaScript
The Foundation HyperText Markup Language (HTML) is the backbone of the web, providing the structure for web pages. Despite its simplicity, HTML laid the groundwork for the web as we know it today.

CSS: Styling the Web. CSS allowed developers to separate content from design, making it easier to maintain and update the look and feel of websites. With CSS, developers could control layout, colors, fonts, and more, bringing a more polished and visually appealing experience to users.

##### JavaScript: Bringing Interactivity
JavaScript, revolutionized the web by enabling interactive features. Unlike HTML and CSS, JavaScript is a programming language that runs in the browser, allowing developers to create dynamic content that responds to user actions. From form validation to interactive maps, JavaScript opened up a world of possibilities for web developers.


The Rise of Libraries and Frameworks

React: The Component Revolution
Facebook's React, introduced in 2013, brought a revolutionary approach with its component-based architecture. React components encapsulate their logic and presentation, making it easier to manage and reuse code. 

Vue.js: The Progressive Framework
Vue.js, created by Evan You in 2014, combined the best of AngularJS and React. Vue is known for its simplicity and flexibility, making it approachable for beginners who probably just decided to move from writing pure javascript to delve into a new javascript framework. Unlike React, Vue is quite very easy for beginners because it uses almost same code-block like pure javascript and still very powerful enough for large-scale applications. Vue's reactive data binding and component-based architecture have made it a favorite among developers plus me in particular. Especially when you are moving from vue to Nuxt which is still Vue but unlike Vue, where you have to import a number of components, Nuxt auto imports these components anytime that you need to use them in a certain code-block.



Conclusion

As much as I am aware that HNG is a React only based Internship which means that I would either have to learn to use react or possibly be evicted out of the race along the line. I would still love to go ahead if given the opportunity to learn alongside others using Vue/Nuxt, if otherwise, I would continue to learn React till I finish or till I am dropped out of the race.

Tags: psychology, communication, bodylanguage
Published: 2024-06-28 20:14:16

# How to Spot a Liar: Understanding Body Language and Verbal Cues 👀🗣️

It can be difficult to tell when someone is lying, but by paying attention to
their body language, tone of voice, and words, you can increase your chances of
detecting deception. Here are some signs that someone may be lying:

## Body Language Signs of Lying 🕵️‍♀️

- **Avoiding eye contact**: Liars often avoid eye contact because they are
  afraid of being caught.
- **Trembling or fidgeting**: Liars may exhibit signs of nervousness, such as
  trembling or fidgeting.
- **Increased blinking**: Liars may blink more frequently than usual.
- **Sweating**: Liars may sweat more than usual.
- **Changes in facial expression**: Liars may exhibit changes in facial
  expression, such as a frown or a smile that doesn&#x27;t reach their eyes.
- **Throat clearing or coughing**: Liars may clear their throat or cough more
  often than usual.
- **Playing with their hair or clothes**: Liars may play with their hair or
  clothes as a way to relieve stress.

## Verbal Cues of Lying 🗣️

- **Changes in tone of voice**: Liars often speak in a higher-pitched or more
  hesitant tone of voice than usual. They may also speak more quickly or slowly
  than usual.
- **Using filler words**: Liars may use filler words or phrases, such as &#x27;um,&#x27;
  &#x27;like,&#x27; and &#x27;you know,&#x27; more often than usual.
- **Making up excuses or changing their story**: Liars may try to cover up their
  lies by making up excuses or changing their story.

## Context and Gut Feelings 🤔

It&#x27;s important to remember that these are just a few of the signs that someone
may be lying. There is no one-size-fits-all method for determining if someone is
being truthful. However, by paying attention to these signs and considering the
context of the situation, you can increase your chances of spotting a liar.

It&#x27;s also important to trust your gut. If you have a feeling that someone is
lying, it&#x27;s probably best to err on the side of caution and assume that they
are.

## Conclusion 🎉

By understanding body language and verbal cues, you can become more skilled at
detecting when someone is lying. Pay attention to a person&#x27;s eye contact, facial
expressions, and gestures, as well as their tone of voice and choice of words.
Remember to also consider the context of the situation and to trust your gut
feelings. By improving your ability to spot a liar, you can become a more
effective communicator and build stronger relationships based on trust and
honesty.
