In javascript we have different methods to remove an element from an array jere we are using the splice method to remove existing elements and/or adding new elements
Using the indexing method we can remove any particular element from the array. Such as
<html> <head> <p>Remove elements from array in JavaScript.</p> </head> <body> <script> var arr = [3, 6, 8]; var index = arr.indexOf(6); if (index > -1) { arr.splice(index, 1); } console.log(arr); </script> </body> </html>
In the above code we have declared an array =[3,6,8] which an indexing of [0,1,2].
Using The indexOf() method which returns the first index at which a given element can be found in the array, or -1 if it is not present. Next we have passed the if condition where index is greater than -1 return arr.splice(index,1) that is remove the 1st index element from the array.
Then when we console log arr we get the array without the 1st element.
[3,8] .
The Splice() method adds and/or removes array elements. This method overwrites the original array.
