Example

document.getElementById('demo').innerText = 'Hello, JavaScript!';

Scenario

Used to dynamically change the text of an HTML element with ID 'demo'. This is commonly used in web applications to update the UI without refreshing the page.

Example

document.addEventListener('click', function() { alert('Element clicked!'); });

Scenario

Adds an event listener to the entire document that triggers an alert message whenever a click occurs. This function is fundamental in interactive web applications, allowing developers to define how the application reacts to user inputs.

Example

fetch('https://api.example.com/data').then(response => response.json()).then(data => console.log(data));

Scenario

Fetches data asynchronously from a specified API and logs it to the console. This is crucial for developing web and mobile apps that rely on data from back-end servers without blocking the user interface.

Example

window.requestAnimationFrame(function animate(time) { /* animation code */ });

Scenario

Utilized for creating animations in web applications. This function allows for smoother and more performant animations by optimizing them to run at the best times for rendering performance.
