How to push to an array in a particular position?

Question

I\'m trying to efficiently write a statement that pushes to position 1 of an array, and pushes whatever is in that position, or after it back a spot.

array =         


        

Answer 1

To push any item at specific index in array use following syntax

// The original array
var array = ["one", "two", "four"];
// splice(position, numberOfItemsToRemove, item)
array.splice(2, 0, "three");

console.log(array);  // ["one", "two", "three", "four"]
