What are Variables?
Variables are the memory locations that are used to store data. In JavaScript, we use the let, const, and var (var is not used now) keywords to declare a variable.
By using let we can re-assign the value to a variable. Values can not be reassigned if they are created using const.
The following statement creates a variable named message.
let message;
Now we can assign some data to the variables by using the assignment operator sign (=), for example.
let message; message = 'Hello'; // or you can do it in one line as well like this // let message = 'Hello'; console.log(message);
