Suppose we are building a game, and we want to keep track of the item names and their in-game prices. We need some variables!

In many cases, you will only assign a variable once, i.e. store a value into it, and then use it without ever changing it. These are the cases where you should use a constant variable.

Constant variables are extremely easy to use in Emojicode:

3.14 ➡️ pi

• 3.14 is the value of the variable.
• ➡️ is the assignment operator.
• pi is the name of the variable.

Here, the value on the left-hand side of the ➡️ is stored into the pi constant variable.

Note: You cannot change a constant variable. If you try to reassign a constant variable, this will result in a compiler error.
