How do I use methods in Vue.js?

In Vue.js, methods are functions that are defined in the methods option of a Vue instance. You can call them in your templates or other methods.

Can you give me an example of a method?

Sure! Here's a simple example:

new Vue({
  el: '#app',
  data: {
    message: 'Hello!'
  },
  methods: {
    greet() {
      return this.message;
    }
  }
});

You can call this.greet() to get the message.

How do I call a method from a button click?

You can use the v-on:click directive in your template. For example:

<button v-on:click="greet">Click me</button>

What if I want to pass parameters to a method?

You can pass parameters directly in the method call. For example:

<button v-on:click="greet('Vue.js')">Click me</button>

And modify the method to accept the parameter.
