Arrays

JavaScript's arrays are similar to Python's lists.

One important thing about JavaScript arrays are that items in an array are not required to be of the same type... Remember, JavaScript is about as loosy-goosy as programming languages get...

const numbers = [1, 2, 3, 4, 5];
const strings = ["banana", "apple", "pear"];
const miscellaneous = [true, 7, "adamantium"];

You can index into an array using square brackets []:

const strings = ["banana", "apple", "pear"];
console.log(strings[0]);
// Prints: 'banana'

And you can .push() new items onto the end of an array:

const drinks = [];
drinks.push("lemonade");
console.log(drinks);
// Prints: ['lemonade']
drinks.push("root beer");
console.log(drinks);
// Prints: ['lemonade', 'root beer']
