And you're equipped with a handy mnemonic, that splice compared to slice has an additional letter, 'p', which helps you remember that splice mutates and optionally adds or removes from the original array. You now know that slice makes a shallow copy of the original array, while splice mutates the original array and optionally adds or removes elements. ConclusionĪnd there we have it! This blog goes over the differences between slice and splice. And because splice can add and remove stuff to the original array, that means that it also mutates the original array.

If you want to remove all occurrences of a given object (based on some condition) then use the javascript splice method inside a for the loop. The splice () method is used to remove or replace existing elements in the array. The slice () method is used to convert an array-like object into an array. splice ( 3, 1, 'juliet', 'zeke' ) // remove 'harper'. Syntax: array.splice ( start,delete,element1,element2.) Parameters: start: It is a required parameter and represents the index from where the function start to fetch the elements.
