JavaScript Array splice vs slice

Question

What is the difference between splice and slice?

Answer 1

They both are JavaScript array functions. splice() changes the original array whereas slice() doesn't but both of them return the array object.

See this examples for splice:

var array=[1,2,3,4,5];
console.log(array.splice(2));

The output should be [3,4,5]. The original array is affected resulting in the array being [1,2].

See this example for slice:

var array=[1,2,3,4,5]
console.log(array.slice(2));

The output should be  [3,4,5]. The original array is NOT affected resulting in the array being [1,2,3,4,5].

I hope this helps you understand the difference between them.
