Create an Array

One way we can create an array is to use an array literal. An array literal creates an array by wrapping items in square brackets []. Remember from the previous exercise, arrays can store any data type — we can have an array that holds all the same data types or an array that holds different data types.

Let’s take a closer look at the syntax in the array example:

  • The array is represented by the square brackets [] and the content inside.
  • Each content item inside an array is called an element.
  • There are three different elements inside the array.
  • Each element inside the array is a different data type.

We can also save an array to a variable. You may have noticed we did this in the previous exercise:

let newYearsResolutions = ['Keep a journal', 'Take a falconry class', 'Learn to juggle'];

Let’s practice by making an array of our own.
