The JavaScript Ternary Operator is a powerful tool for developers, allowing for concise conditional expressions in code. It uses a simple syntax: condition ? expressionIfTrue : expressionIfFalse, enabling inline decisions and variable assignments based on conditions. This operator is ideal for simple decision-making, offering a more elegant alternative to if-else statements. However, it's important to use it judiciously to maintain code readability and avoid complexity in maintenance.
