![]() ![]() I think you can do the same in other languages as well, such as JavaScript, as it also has array.splice operation. I'll leave these other operations as an exercise to the reader. There are more operations that you can do with splice, such as deleting all elements in the array, adding elements at the i-th position. Let's say you've array array now contains: At the same, it will reduce the length of the array by one. Moreover, this function returns the removed element. ![]() To push to an array via splice, you need to set offset to the end of the array, length to anything, and list to the list of values that you want to add. JavaScript Array pop() Array.pop(): We use pop JavaScript to remove the last element in an array. Offset, length, and list can be omitted, which makes it a really powerful function that can do a bunch of array operations. Splice replaces length elements in array at offset with list. So I thought I'd write a blog post that shows how awesome splice is. Someone asked me today about Perl array operations and it turned out he didn't know that all basic array operations, such as push, pop, shift, unshift can be implemented with just splice. ![]()
