Vue Js Sum of All Elements/Number of Array: To find the sum of all elements/numbers in a given array in Vue.js, you can use the reduce
method. This method applies a function to each element of the array, accumulating a single value from left to right.
You can define a method in your Vue component that takes in the array as a parameter and then uses the reduce
method to sum up all the elements in the array. The method should return the final sum.
How can you use Vue.js to add up all the items in an array?
This code is using Vue.js, a JavaScript framework, to display an array and its sum in a web page.
The Vue instance is created with a “data” property that holds an array of numbers called “myArray”. This array is displayed in the web page using Vue’s template syntax.
The Vue instance also defines a “methods” property with a function called “sumArray”. This function uses the “reduce” method to sum up the numbers in the array.
In the web page, the sum of the array is displayed by calling the “sumArray” function and passing in “myArray” as an argument using Vue’s template syntax.
Vue Js Add of all items of Array Example
<div id="app">
<p>Array: {{ myArray }}</p>
<p>Sum: {{ sumArray(myArray) }}</p>
</div>
<script type="module">
const app = new Vue({
el: "#app",
data() {
return {
myArray: [11, 22, 13, 44, 15],
}
},
methods: {
sumArray(arr) {
return arr.reduce((total, num) => total + num, 0);
}
}
});
</script>
