Digging deeper into strings, JavaScript math, arrays, and objects

My Strings, Arrays, and Objects pocket guide had gotten really large and was still missing important information.

Last week, I split it into two new guides: Strings & Numbers and Arrays & Objects.

Strings & Numbers includes more details on the template literal syntax, basic arithmatic, and more complex math with JavaScript. Arrays & Objects goes into more detail on modern Array methods like map(), filter(), and reduce().

And there’s a new project: a JS tip calculator app.

You can watch sample lessons for Strings & Numbers and Arrays & Objects.
