Javascript setInterval vs setTimeout

In this post, we will learn more on javascript scheduling task with setInterval and setTimeout:

setTimeout and setInterval are both JavaScript functions used to schedule the execution of code after a specified amount of time has passed.

Using SetTimeout:

• setTimeout is used to run a function once after a specified amount of time has passed
• It takes two arguments: the first argument is the function to be executed,
• the second argument is the time in milliseconds to wait before executing the function

Example:

setTimeout(function() {
  console.log("Hello World!");
}, 5000);

setTimeout(()=>{ console.log("Hello World");},5000);

Using SetInterval:

setInterval is used to run a function repeatedly at specified intervals

setInterval(function() {
  console.log("Hello World!");
}, 5000);
const x = setInterval(()=>{ console.log("printed");},10);

In this example, the code inside the setInterval function will run every 5 seconds, continuously until the clearInterval method is called to stop it.

clearInterval(x)

• setTimeout is used to run a function once after a specified amount of time
• setInterval is used to run a function repeatedly at specified intervals.
