And this method changes the contents of the original arrays.
It removes existing data element and/or adds a new item to the array. So, the next function we’ll gonna look at is the splice function. To have the ability to take that portion array.slice can work with two arguments (see the Difference #3). It returns a shallow copy of a portion of an array into a new array. Array.slice and array.splice are those two frequently used methods that will be required to access and change data inside those arrays.įirst let’s take a look at slice method. For example, images for galleries, banners, temporary user data, etc. JavaScript arrays are frequently used to store different types of data. We’ve decided to take a “programming” topic for a change and fill in some blank places in JavaScript development topic Specifically we’ll describe Array Splice and Slice methods, how you can use this stuff, and what the difference between them.
