Has an overview of basic STRING methods that are incredibly useful and I would suggest looking over them and trying to remember what each does. The best way to really understand what they do is to practice with them, so try all the given examples and come up with your own!
Methods covered:
- indexOf
- substring
- toUpperCase
- toLowerCase
- charAt
- charCodeAt
- split
- length
Methods covered:
- slice
- splice
- pop
- push
- shift
- unshift
- concat
- join
There is an example for each of the methods, and for indexOf, filter, forEach, map, and reduce there is also an example for how to do the same thing without the advanced method. This is so that you can understand what the method does behind the scenes.
Methods covered:
- sort
- reverse
- every
- some
- indexOf
- filter
- forEach
