Booleans

Let's explore our last data type for this section, booleans.

Explore:

1. Guess what the types of each of these pieces of data are before running the code.

// Let's look at examples of our three types: strings, numbers, and booleans.
console.log(typeof "Hello, world!");
console.log(typeof 293);
console.log(typeof true);
console.log(typeof false);
// Note that when number, true, or false are surrounded by quotes that it is a string.
console.log(typeof "true");
console.log(typeof "293");

Comparison operators

Let's see how to compare two pieces of data.

Explore:

1. Try different numbers for a and b.
2. Try one variable being a number wrapped in quotes.

// Here are all the comparison operators
// Three of these will return true with a = 7 and b = 7. Guess which ones!
let a = 7;
let b = 7;
console.log(a === b);
console.log(a !== a);
console.log(a < b);
console.log(a > b);
console.log(a <= b);
console.log(a >= b);
