Difference between @click and v-on:click Vuejs

The questions should be enough clear.

But I can see that someone use:

<button @click="function()">press</button>

Someone use:

<button v-on:click="function()">press</button>

But really what is the difference between the two (if exists)

v-bind and v-on are two frequently used directives in vuejs html template. So they provided a shorthand notation for the both of them as follows:

You can replace v-on: with @

v-on:click='someFunction'

as:

@click='someFunction'

Another example:

v-on:keyup='someKeyUpFunction'

as:

@keyup='someKeyUpFunction'

Similarly, v-bind with :

v-bind:href='var1'

Can be written as:

:href='var1'

Official source

The official Vue.js style guide recommends sticking with one version and keeping it consistent.

Directive shorthands (: for v-bind:, @ for v-on: and # for v-slot) should be used always or never.

This rule is defined in the Strongly Recommended section.

It can be enforced with eslint by using the eslint-plugin-vue plugin and setting the vue/v-on-style rule.

Default is set to shorthand.

{
  "vue/v-on-style": ["error", "shorthand" | "longform"]
}

Example

<template>
  <!-- ✓ GOOD -->
  <div @click="foo"/>

  <!-- ✗ BAD -->
  <div v-on:click="foo"/>
</template>

They may look a bit different from normal HTML, but : and @ are valid chars for attribute names and all Vue.js supported browsers can parse it correctly. In addition, they do not appear in the final rendered markup. The shorthand syntax is totally optional, but you will likely appreciate it when you learn more about its usage later.

There is no difference between the two, one is just a shorthand for the second.

The v- prefix serves as a visual cue for identifying Vue-specific attributes in your templates. This is useful when you are using Vue.js to apply dynamic behavior to some existing markup, but can feel verbose for some frequently used directives. At the same time, the need for the v- prefix becomes less important when you are building an SPA where Vue.js manages every template.

<!-- full syntax -->
<a v-on:click="doSomething"></a>
<!-- shorthand -->
<a @click="doSomething"></a>
