How can I pass arguments to the callback function in setTimeout

Question

With the help of a proper code explanation, can you tell me How I can pass arguments to the callback function in setTimeout()?

Answer 1

You can pass arguments to the callback function in setTimeout() by using anonymous functions or arrow functions.

1. Using an anonymous function (or arrow function):

You can pass arguments by wrapping your callback in an anonymous function or an arrow function, which then calls the actual callback with the desired arguments.

Example:

function greet(name) {

  console.log('Hello, ' + name);

}

// Using setTimeout with an anonymous function

setTimeout(function() {

  greet('Alice');

}, 1000);

// Or using an arrow function

setTimeout(() => greet('Bob'), 2000);

2. Using bind() method:

You can also use the bind() method to pre-assign arguments to your callback function before passing it to setTimeout().

Example:

function greet(name) {

  console.log('Hello, ' + name);

}

setTimeout(greet.bind(null, 'Charlie'), 3000);
