What is the best way to omit the final item in a v-for loop?

I'm just starting out with JavaScript and learning about JS frameworks. I recently came across this snippet of Vuejs code:

<div v-for="coefficient in coefficients" class="coefficient">
    <div>
        <span class="name">name:{{coefficient.name}}</span>
        <span class="value">value:{{coefficient.value}}</span>
        <span>---</span>
    </div>
</div>

When I run this code, I get the following output:

name: Ubuntu
value: 1
---
name: MacOS
value: 2
---
name: Windows
value: 3
---

Now, my question is how can I remove the last item from the coefficients array using Vuejs?

Answer №1

simply employ the

v-for="value in values.slice(1,-2)"

example

Answer №2

You have the option to utilize a computed property or use coefficients.slice(0, -1) in this manner:

new Vue({
  data : {
    coefficients : [
    {name : "a", value : 2}, 
    {name : "b", value : 3}, 
    {name : "c", value : 4}]
  },
  el : "#app"  
})
<div id="app">
    <div v-for="coefficient in coefficients.slice(0, -1)" class="coefficient">
        <div>
            <span class="name">name:{{coefficient.name}}</span>
            <span class="value">value:{{coefficient.value}}</span>
            <span>---</span>
        </div>
    </div>
</div>
