In programming there are different types of data. You've used one data type already: string.

Computers recognise strings as a sequence of characters but to humans, strings are simply lines of text.

var message = "This is a string";

Notice that strings are always wrapped inside of quote marks. We do this so that the computer knows when the string starts and ends.

You can check that the data is a string by using the typeof operator:

var message = "This is a string";
var messageType = typeof message;

console.log(messageType); // logs 'string'

Exercise

• Write a program that logs a message and its type

Expected result

This is a string
