JavaScript arrays allow you to group values and iterate over them. You can add and remove array elements in different ways. Unfortunately, there is not a simple Array.remove method. Here are some ways to remove an element from the array
- pop
- shift
- splice
- remove the specific element with splice
1. pop
The pop() method removes the last element of an array, and returns that element.
let fruits = ["🍓","🍊","🍇","🍎"]; fruits.pop(); console.log(fruits); // [🍓,🍊,🍇]
2. shift
The shift() method removes the first item of an array. The shift() method changes the original array.
let fruits = ["🍓","🍊","🍇","🍎"]; fruits.shift(); console.log(fruits); //[🍊,🍇,🍎]
3. splice
The splice() method adds/removes items to/from an array, and returns the removed item(s). Splice also changes the original array.
let fruits = ["🍓","🍊","🍇","🍎"]; fruits.splice(1,2); console.log(fruits); //[🍓,🍎]
4. Remove specific element with splice
let fruits = ["🍓","🍊","🍇","🍎"];
let applesPos = fruits.indexOf("🍎");
fruits.splice(applePos, 1);
console.log(fruits);
//[🍓,🍊,🍇]Thanks for scrolling & Share this blog, if you have liked it. You can read our other blogs here.
