13 ternary operator in javascript

the ternary operator in javascript is a concise way to perform conditional evaluations and is often used as a shorthand for the if-else statement. it takes three operands: a condition followed by a question mark `?`, then the expression to execute if the condition is true, followed by a colon `:`, and finally, the expression to execute if the condition is false. this operator allows developers to write cleaner and more readable code, especially for simple conditions.

javascript's ternary operator can be nested, enabling multiple conditions to be checked in a single line, although this can decrease readability if overused. it's commonly employed in setting default values, rendering ui components based on conditions, or simplifying return statements. while it enhances brevity, developers should use it judiciously to maintain code clarity and ensure that complex conditions are handled with traditional control structures for better understanding and maintainability.
