How can I remove an array element by index,using javaScript?

Question

fruits = ["mango","apple","pine","berry"];

If I want to remove an element index wise, How to do that using JavaScript. Also you can use library as required.

Answer 1

You can use splice to do the same. Syntax = array.splice(start_index, no_of_elements) Following is the command:

const fruits = ["mango","apple","pine","berry"]; // returns mutated array
const removed = fruits.splice(2, 1); // returns array of removed items
console.log('fruits', fruits);
console.log('removed', removed);

This will remove one element from index 2, i.e. after the operation fruits=["mango","apple","berry"];
