What is the process of creating a temporary variable in the Vue.js template?

edit

There are different ways to create a temporary variable in Vue.js template, but one common approach is to use a computed property.

Here is an example of how to define a computed property as a temporary variable:

<template>
  <div>
    <p>The sum of {{ num1 }} and {{ num2 }} is {{ total }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      num1: 5,
      num2: 10
    }
  },
  computed: {
    total() {
      let sum = this.num1 + this.num2
      return sum
    }
  }
}
</script>

In this example, we define a computed property called "total" that calculates the sum of "num1" and "num2". We can then use "total" as a temporary variable in the template and display its value. The computed property will be re-evaluated whenever "num1" or "num2" changes.

Another approach is to use a method to compute the value of a temporary variable, but this may be less efficient because the method will be called every time the template re-renders.
