JavaScript setTimeout() method

The setTimeout() method in JavaScript is used to schedule the execution of a function or the evaluation of an expression after a specified delay (in milliseconds). It is a way to introduce a time delay in your code. Here’s the syntax:

setTimeout(function, delay, param1, param2, ...)

• function: The function to be executed after the delay. This can be either a function reference or an anonymous function.
• delay: The delay (in milliseconds) after which the function should be executed.
• param1, param2, ... (optional): Additional parameters to be passed to the function.

Here’s an example that demonstrates the usage of setTimeout():

function greet(name) {
  console.log("Hello, " + name + "!");
}

setTimeout(greet, 2000, "John");

In this example, the greet() function will be executed after a delay of 2000 milliseconds (2 seconds), and it will print “Hello, John!” to the console.

Note that you can also use an anonymous function as the first parameter of setTimeout():

setTimeout(function() {
  console.log("Delayed function executed");
}, 3000);

In this case, the anonymous function will be executed after a delay of 3000 milliseconds (3 seconds).
