How to comment out in JavaScript?

To comment out in JavaScript, put // in front of the line.

Here's how you do it:

console.log('This is NOT commented out');

// console.log('This is commented out');

console.log('This is NOT commented out');

Multiple lines

To comment out multiple lines without adding // to every line, put /* at the start and */ at the end like so:

console.log('This is NOT commented out');

/*
console.log('This is commented out');
console.log('This is commented out');
console.log('This is commented out');
console.log('This is commented out');
console.log('This is commented out');
*/

console.log('This is NOT commented out');
