Creating arrays

Arrays consist of square brackets and items that are separated by commas.

  1. Suppose we want to store a shopping list in an array. Paste the following code into the console: 

    2. const shopping = ["bread", "milk", "cheese", "hummus", "noodles"];
console.log(shopping);
  2. In the above example, each item is a string, but in an array we can store various data types - strings, numbers, objects, and even other arrays. We can also mix data types in a single array - we do not have to limit ourselves to storing only numbers in one array, and in another only strings. For example: 

    const sequence = [1, 1, 2, 3, 5, 8, 13];
const random = ["tree", 795, [0, 1, 2]];
  3. Before proceeding, create a few example arrays.
