In removing the elements, it takes two parameters, the first parameter is the element index to start the elimination and the second parameter is the number of elements to be eliminated. The splice method changes an array by adding or removing elements from it.

The name is similar to slice(), thus the confusion to some beginners including myself.

Let newArray = array.slice(0,3) //means start slicing from index 0 until you get to index 3 Let array = įor example, I want to slice the first three elements from the array Always remember that first elements are zero indexed. It accepts two arguments, the first argument is the element index to start slicing while the second argument is the element index to stop but does not include that element( tricky part). The slice() method selects a given part of an array and returns that selected part as a new array without changing the original array. Now let’s dive into the JavaScript built in methods: Slice(), Splice() and Split() Javascript Array is a special variable which can hold more than one value at a time.
