you need to create a name for your variable so that it can be accessed within your Javascript code. You start off with var/let/const, then the name of your variable. If you want to give it a value, add an equal sign and then add your value.

// this creates a variable named answer, but does not assign it a value.
var answer;

// this creates a variable named answer and assigns it a value.
var answer = "answer";

// if you want to change the value of your variable, remove the identifier (var/let/const) and then set it equal to a value.
answer = "answer";

// you can also use this variable in a method. for example, this will pop up an alert in your web page
// whatever your variable is set to (the value after the equals sign) will appear wherever you place your variable.
window.alert(answer);
