JavaScript provides a built-in method setTimeout() to wait X seconds based on user needs. The output shows the executable code and displays “Welcome to JavaScript.” After waiting for 3 seconds, the message “Welcome to Linuxhint” is displayed in the console window. In the end, the setTimeout() method is employed by passing the milliseconds “ms”.In the sleep() method, the “Promise” object is employed to execute the operation in an asynchronous way.In this method, “3000” milliseconds are passed to the sleep() method for delaying 3 seconds.The “ wait” method is employed in an asynchronous way.The description of the code is given below: Return new Promise (val = > setTimeout (val, ms ) ) Note: 1000 milliseconds refer to 1 second.Ĭonsole.log ( 'An example to wait 3 seconds in JavaScript' ) While the other arguments represent the number of milliseconds that delay the execution. The first argument refers to the callback function, which executes when the time expires. The setTimeout() method takes two parameters as arguments. The method takes input time in milliseconds and delays the execution defined by the user. The setTimeout() method executes the piece of code when the time expires. How to Wait for X Seconds Using setTimeout() Method? Example 2: Wait for 3 Seconds in JavaScript.Example 1: Wait for 5 Seconds in JavaScript.How to Wait for X Seconds Using setTimeout() Method.The article demonstrates the way to wait for X seconds during code execution with the following learning outcomes:

The method has the facility to wait for x seconds during the code execution to serve the specific purpose of the programmer. However, JavaScript achieves this task using the setTimeout() method.

JavaScript is unable to use this method due to its asynchronous nature.

Spoiler: JavaScript never really 'pauses'.Modern programming languages support the sleep() method to wait for the execution of a program. In this post, I'll discuss how you can achieve that and what it really means to 'pause' or 'sleep' in JavaScript. One of those features are Promises, which are probably the most widely used feature in JavaScript after ES5 was released.īut one of the things which JavaScript misses is a way to 'pause' execution for a while and resume it later. More and more ideas and features are being ported from different languages and being integrated in JavaScript. And it hasn't been the same since ES5 was released.
