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

Question

How to remove an array's element by its index?

For example

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

Remove element fruits[2] to get

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

Answer 1

You can use splice as: array.splice(start_index, no_of_elements_to_remove). Here's the solution to your example:

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

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