You can think of variables as a way to store information that might be needed on an application.
To define a variable, you can use var
, let
, or const
!
var myFavoriteNumber = 7
let myFavoriteFood = "Cereal"
const myFriendsName = "John"
The variable myFavoriteNumber
contains the number 7.
The variable myFavoriteFood
contains the word "Cereal"
The variable myFriendsName
contains the word "John"
An Example
Lets say you're trying to remember what your friends name is. An easy way to keep this information in your application would be creating a variable and storing your friends name inside of it!
So our exact steps would be:
- Create a variable
- Assign it the value of your friends name
