How to delete a specific element from array? with String Index

Question

How to remove/delete a specific element from an array with as index a string instead of numbers? this is my code:

workout.program = new Array();
workout.program["first"] = new Array();
workout.program["first"]["time"] = 10;
workout.program["first"]["speed"] = "medium";
workout.program["first"]["slope"] = 0;

So it's about a 2d Array, and i want to delete everything which is under program["first"] including to delete that Array. How to do this in pure JavaScript without JQuery?

If you're going to be accessing elements with strings, maybe consider using a dictionary? — Tyler

It's an object not an array, so use:

delete workout.program.first;

You access arrays using a numerical index, objects by keys. workout is an object. workout.program is an object, and workout.program.first is an object, despite you trying to code it as an array.
