πŸ€” Did you know?

Google was almost called Backrub when it first started! 😲

The name came from its focus on analyzing backlinks to measure a website's importance. But imagine saying, "Let me Backrub that!" πŸ˜‚ Doesn't quite have the same ring, does it?

Luckily, they switched it to Google, inspired by the term googol (the number 1 followed by 100 zeros), representing their mission to organize an endless amount of information! 🌐✨

πŸš€ Web Tip: Why You Should Add Version Numbers to Your CSS & JavaScript Files πŸ§‘β€πŸ’»

When working on a website, adding version numbers to your CSS and JS files is crucial! Here's why:

1️⃣ Cache Busting:
Browsers cache your files to improve performance. But this can be problematic when you update your CSS/JS. By adding a version number (e.g., style.css?v=1.2), you ensure that users always get the latest version, not a cached one.

2️⃣ Easy Updates:
When you release a new update, changing the version number guarantees that users will fetch the newest files instead of relying on the old cached versions.

3️⃣ Debugging Made Easy:
Versioning helps identify which version of a file is causing issues, making debugging simpler.


πŸ’‘ Tip: Use a query string with each file update like style.css?v=1.3. You can automate versioning with build tools!

Want to make your web pages interactive?
Mastering DOM manipulation is essential! πŸ’»βœ¨

The DOM (Document Object Model) represents the structure of your HTML page.

With JavaScript, you can:

πŸ”Ή Access elements:
 const heading = document.getElementById("main-title");


πŸ”Ή Change content:

heading.textContent = "Hello, DOM!";

πŸ”Ή Update styles:

heading.style.color = "blue";

πŸ”Ή Create elements:

const newDiv = document.createElement("div");
document.body.appendChild(newDiv);


πŸ”Ή Listen for events:

button.addEventListener("click", () =>alert("Clicked!"));

πŸ’‘The DOM isn’t part of JavaScript β€” it's provided by the browser! JavaScript just gives us the tools to work with it. 🀯

πŸš€ JavaScript Strict Mode:

Did you know JavaScript has a "strict mode" that helps you write safer and more optimized code? πŸ”

What is 'use strict'?

Adding 'use strict'; at the top of your script or function enforces stricter parsing and error handling, preventing common mistakes.

Benefits of Strict Mode:

βœ”οΈ Catches silent errors by turning them into throw errors
βœ”οΈ Prevents accidental global variables
βœ”οΈ Disallows duplicate parameter names
βœ”οΈ Makes eval() and arguments safer
βœ”οΈ Restricts deprecated features

How to Use It?

Simply add this at the beginning of your script or function:

'use strict';


function testStrict() {
let x = 10;
console.log(x);
}


πŸ”— Pro Tip:

Always use strict mode for cleaner, more reliable JavaScript!
