arr.splice(2, 1, 'tmp');	// Replaces 1 item at index 2 with 'tmp'
// => ['foo', 10, 'tmp']

Example 2: splice in javascript

Splice and Slice both are Javascript Array functions. Splice vs Slice. The splice() method returns the removed item(s) in an array and slice() method returns the selected element(s) in an array, as a new array object. The splice() method changes the original array and slice() method doesn't change the original array.27-Jan-2018
