2 Crucial Insights Every Developer Should Know

If you just started your career in tech or you are in the development industry these few crucial Insights I recommend to you...

You know what when I started programming in 2018 the first thing I learn is the Windows command while learning CS50 Harvard University (Online Courses) in the beginning it was boring but a few months later it helped me to learn git.

*The command line interface (GIT) offers several advantages over graphical user interfaces (GUI) in many development scenarios.
*

1. Master Version Control

Using GIT often requires a deeper understanding of system operations, which can be beneficial for developers in the long run

GIT commands can be executed much faster than navigating through multiple GUI menus.

Resource usage:

CLI typically uses fewer system resources than GUI applications, which is beneficial when working on remote servers or less powerful machines.

Remote access:

When working with remote servers, CLI is often the only or the most efficient way to interact with the system.

Scriptability

Text processing

Integration

Consistency across systems

Learning and understanding
*Here are some basic commands *

git init: Initializes a new Git repository.
git clone <repository_url>: Clones an existing repository.
git add <file>: Adds a file to the staging area.
git commit -m "Commit message": Commits changes to the local repository.
git push <remote> <branch>: Pushes changes to a remote repository.
git pull <remote> <branch>: Pulls changes from a remote repository.

2. Prioritize Code Readability

Why readable code matters:
Readability makes code easier to understand, debug, and maintain

Clever code may save a few lines but hurts long-term maintainability

Future developers (including your future self) will thank you!

// Function to calculate the square of a number
/**
 * Calculates the square of a given number.
 * 
 * @param {number} num - The number to square.
 * @returns {number} The square of the input number.
 */
function square(num: number): number {
  // Check for valid input 
  if (typeof num !== 'number') {
    throw new Error('Input must be a number');
  }

  return num * num;
}

// Example usage
const result = square(5);
console.log(`The square of 5 is: ${result}`);

This code:

1) Has a clear, descriptive function name
2) Uses JSDoc comments to explain the purpose and parameters
3) Includes type annotations for the parameter and return type
4) Includes a basic input validation check
5) Keeps the function short and to the point
6) Uses consistent formatting and indentation
