Welcome to the lesson on IDEs, Variables, and Conditionals! This README serves as a reference tool to review key points and includes code snippets to help reinforce learning.

• CodeSandbox Introduction
• Variables in JavaScript
• Technical Questions
• JavaScript Math
• Conditionals in JavaScript
• Feedback & Resources

• Online editor tailored for rapid web development.
• Quickly prototype, experiment, share, and debug your code.
• Supports multi-page websites and various frameworks or libraries.
• Collaborative coding enabled through live sharing.

1. Login: Go to CodeSandbox -> Sign In using GitHub.
2. Creating a Sandbox:
   • Click Create -> Choose Vanilla from Official Templates.
   • Your new sandbox will load up with an index.html file ready to edit.
3. Navigating: The left navigation panel provides access to various features such as:
   • Sandbox Info, Explorer, Search, Configuration Files, GitHub Integration, Deployment options, and Live collaboration.

Note: For detailed exploration of CodeSandbox, follow the teacher's guide provided in the lesson.

Variables are containers that store data values.

let box;

box = 10;
// or
let box = 10;

box = 15;  // Now, box has a value of 15

Note: Variable names should be descriptive, can't start with a number, and can't use JS keywords.

• Contextualize your question: explain what you're trying to achieve.
• Specify the problem and indicate any solutions you've already tried.
• Sharing your code can often help in resolving the issue faster.

Example: Instead of saying "My code doesn't work", you might say: "I'm trying to fetch user data from an API using JavaScript, but I'm getting a 404 error. I've checked the endpoint URL, and it seems correct. Can someone take a look at my fetch function?"

Basic arithmetic works intuitively:

5 + 2  // 7
5 * 2  // 10
5 - 2  // 3
5 / 2  // 2.5

Example with Variables:

let myNumber = 12;
myNumber / 3  // 4

Conditionals allow you to execute different code branches based on conditions.

Basic if Statement:

if (myNum === 8) {
    console.log("8 is great!");
}

if-else Statement:

if (myNum === 8) {
    console.log("8 is great!");
} else {
    console.log("That number is OK.");
}

if-else if-else Statement:

if (myNum === 8) {
    console.log("8 is great!");
} else if (myNum < 10) {
    console.log("Wow. Less than 10?");
} else {
    console.log("That number is OK.");
}

Happy coding!
