JavaScript Array Type

The Array type is a complex data type where there is fixed relationship between an integer index and property of the type.

Arrays are used to create lists of JavaScript types. As JavaScript developers, we'll meet arrays in pretty much every file we look at, so it's important to have a solid understanding of how they work and what we can do with them.

In this lesson we are going to look at:

1. Creating arrays.
2. Extracting data.
3. Inserting data.
4. Removing data.
5. Finding elements that satisfy some condition.
6. Transforming the elements within them.
