I recommend you try your solutions to exercises in an actual JavaScript interpreter. That way, you’ll get immediate feedback on whether what you are doing is working, and, I hope, you’ll be tempted to experiment and go beyond the exercises. net/ . There, you can click any code example to edit and run it and to see the output it produces. net/code/ , which provides starting code for each coding exercise and allows you to look at the solutions.

This is convenient. You don’t have to gather building material for your values or pay for them. You just call for one, and woosh, you have it. They are not created from thin air, of course. Every value has to be stored somewhere, and if you want to use a gigantic amount of them at the same time, you might run out of bits. Fortunately, this is a problem only if you need them all simultaneously. As soon as you no longer use a value, it will dissipate, leaving behind its bits to be recycled as building material for the next generation of values.
