Implement Closures

In this activity you will work on this user story:

• As a developer, I want to demonstrate my knowledge of closures by creating a makeCountDown function that accesses the surrounding function state.

Your Task

• It's done when I have created a function makeCountDown that returns a nested function.

• It's done when I have set the return value of countDown to a variable called countingDown.

• It's done when invoking the countingDown for the first time will start a countdown from startingNum.

• It's done when every subsequent invocation of countDown returns the startingNum subtracted from the decreasedBy variable.

Notes

• Refer to the MDN Documentation on Closures

Hints

• How can we use the comments inside index.js to guide us in what our inner function should return?

• What kind of function is one that creates other functions?

Bonus

• Using Google, what are some complications you might run into when using closures within for loops?
