Task: Work with Numbers and Strings in your JavaScript programs

Working with numbers and strings in JavaScript is so common that we hardly even think about it. This is especially true since so much of JavaScript involves getting strings of input from users (in Web pages or HTTP requests) and then converting those strings to numbers.

JavaScript tries to be helpful and hide the differences between numbers and strings from us, but that can end up being surprising in rare cases so most JavaScript programmers tend to explicitly avoid those features.

This task will show us what's possible with numbers and strings, including the operators, functions, and methods that can be used to manipulate them.
