In this short post, we will see how to use the setTimeout() function in Vue Js.

The setTimeout() function method executes a function or a block of code after a specific time.

Syntax:

setTimeout(function, milliseconds);

Here, 1000 miliseconds = 1second

The setTimeout is useful to run a function after a specified time delay or sometimes we can use it to emulate a server request for some demos.

Now let's see how we can use the setTimeout() in a Vue method to change the text of a variable.

<template>
  <div id="app">
    <button @click="changeText()">Change Text</button>
    <h1>{{ text }}</h1>
  </div>
</template>

<script>
export default {
  name: "App",
  data() {
    return {
      text: "Hello World",
    };
  },
  methods: {
    changeText() {
      setTimeout(() => {
        this.text = "Welcome World";
      }, 2000);
    },
  },
};
</script>

Here, we have a function changeText(), which have a setTimeout() function that change the text after 2 seconds.

So now when we click the button, it executes the changeText() method, and the this.text changes to 'Welcome World' after a delay of 2 seconds.
