vue mounted vs created

created() : since the processing of the options is finished you have access to reactive data properties and change them if you want. At this stage DOM has not been mounted or added yet. So you cannot do any DOM manipulation here

mounted(): called after the DOM has been mounted or rendered. Here you have access to the DOM elements and DOM manipulation can be performed for example get the innerHTML:

mounted in vue js

Mounted is the most-often used hook in the lifecycle. mounted() is called
after DOM has been mounted so you can access  the reactive component,
templates, and DOM elements and manipulate them.
In Server Side Rendering created()is used over mounted() because 
mounted() is not present in it.
  
  
  
<template>
  <p>I am text inside the component.</p>
</template>

 

<script>

export default {

  mounted() {

    console.log(this.$el.textContent) // I'm text inside the component.

  }

}

</script>
