The J operator

The J operator is a concept in programming languages like JavaScript used to toggle a boolean value, typically for controlling states such as showing or hiding elements. When applied, it switches a value from true to false or vice versa, streamlining state management. Think of it as a toggle switch: if the state is "on" (true), applying J turns it "off" (false); if it's "off" (false), applying J turns it "on" (true). This operator simplifies code by replacing multiple conditional statements with a single, concise toggle action.
