# Prevent magic numbers from being used as a variable name (`magic-variables/no-magic-variables`) I have noticed that developers are lazy and even though the no-magic-numbers rule may in place developers will at times use variables that are the string representation of the magic number. ## Rule Details This rule aims to prevent developers from using variables names that are numeric Examples of **incorrect** code for this rule: ```js var ZeroPointTwoFive = 0.25; ``` Examples of **correct** code for this rule: ```js var UNAUTHORIZED = 401; ```
