remove a item in array js code example

Example 1: javascript removing items looping through array

var colors=["red","green","blue","yellow"];
//loop back-words through array when removing items like so:
for (var i = colors.length - 1; i >= 0; i--) {
    if (colors[i] === "green" || colors[i] === "blue") { 
        colors.splice(i, 1);
    }
}
//colors is now  ["red", "yellow"]

Example 2: remove a particular element from array

var colors = ["red","blue","car","green"];
var carIndex = colors.indexOf("car");//get  "car" index
//remove car from the colors array
colors.splice(carIndex, 1); // colors = ["red","blue","green"]

Example 3: javascript remove first item from array

var colors = ["red", "green", "blue"];
var red=colors.shift();
//colors is now ["green","blue"];

Example 4: javascript remove element from array

const cars = ['farrari', 'Ice Cream'/* It is not an car */, 'tata', 'BMW']

//to remove a specific element
cars.splice(colors.indexOf('Ice Cream'), 1);

//to remove the last element
cars.pop();

Example 5: how can i remove a specific item from an array

const items = ['a', 'b', 'c', 'd', 'e', 'f']
const i = 2
const filteredItems = items.slice(0, i).concat(items.slice(i + 1, items.length))
// ["a", "b", "d", "e", "f"]
