Remove Specific Item From an Array in JavaScript

This tutorial shows how to remove specific item from an array. In JavaScript, we can achieve this by using two ways.

• ECMAScript 5 using filter
• Using indexOf and splice

Example 1: ECMAScript 5 using filter

let removeValue = 3

let arr = [1, 2, 3, 4, 5, 3]

arr = arr.filter(function(item) {
    return item !== removeValue
})

console.log(arr)

This can remove multiple items from the array with the same value using the filter() method.

Output

[ 1, 2, 4, 5 ]

Example 2: Using indexOf and splice

const array = [1, 2, 3, 4, 5];
let removeValue = 3;

const index = array.indexOf(removeValue);
if (index > -1) {
  array.splice(index, 1);
}

console.log(array); 

This way can only remove single value. The indexOf() method gets the position of the value to be removed. The splice() method removes single value from that point.

Output

[ 1, 2, 4, 5 ]
