You can think of variables as "storage containers" for data in your code.

A variable is a "named storage" for data. You can use variables to store goodies, visitors, and other data.

To create a variable in JavaScript, use the let keyword.

The statement below creates (in other words: declares) a variable with the name "message":

let message;

Now, you can put some data into it by using the assignment operator =:

let message;

// store the string 'Hello' in the variable named message
message = 'Hello'; 

To be concise, you can combine the variable declaration and assignment into a single line:

let message = 'Hello';
