splice Array Method | JavaScript Tutorial

Показать описание

In this tutorial, we're going to learn about the #splice #JavaScript #Array Method and how it can be used to remove or replace existing items and/or add new elements inside an array.

Keep in mind that the splice method will change the array on which is called upon, which might not be the best idea always.

Quick note for those who were wondering and love to play around with the code:

// insert an array
const numArr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const removedElems = numArr.splice(5, 3, ["a", "b", "c"]);
console.log(removedElems);
console.log(numArr); // [ 1, 2, 3, 4, 5, [ "a", "b", "c" ], 9, 10 ]

// using the spread operator
const numArr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const removedElems = numArr.splice(5, 3, ...["a", "b", "c"]);
console.log(removedElems);
console.log(numArr); // [ 1, 2, 3, 4, 5, 'a', 'b', 'c', 9, 10 ]

hey thanks man for such simple explanation

Is there not a way to remove individual elements from an array without setting a range in splice? I prefer delete, but the problem is that it leaves an empty spot where the value used to be.

Simply trying to loop through an array of values, splice will not just remove the values that match a regex.

How do you use the terminal there like you're doing? I have to use HTML then script then open in live server but the way you're doing it is so much easier
