Introduction: The Silent Decision-Makers in Your Code Imagine you're building a calculator. You enter two numbers. You press a button. You expect a result. Behind that simple action lies something powerful — operators . Operators are the symbols that allow JavaScript to perform calculations, compare values, make decisions, and update data . They are small, but they drive almost every meaningful line of logic in your program. If variables store data, operators are what make that data useful for operations.
