js splice remove element code example

Example 1: remove an element from array

var colors = ["red", "blue", "car","green"];

// op1: with direct arrow function
colors = colors.filter(data => data != "car");

// op2: with function return value
colors = colors.filter(function(data) { return data != "car"});

Example 2: pop up element from specific index in array

let index = items.indexOf('a')
let numberOfElementToRemove = 1;
if (index !== -1) { items.splice(index,numberOfElementToRemove)}
