Learn the basics of the JavaScript Ternary Operator

The ternary operator is the only operator in JavaScript that works with 3 operands, and it’s a short way to express conditionals.

This is how it looks:

<condition> ? <expression> : <expression>

The condition <condition> is evaluated as a boolean, and upon the result, the operator runs the first expression (if the condition is true) or the second.

This is an example: we check if running equals to true, and if this is the case we call the stop() function. Otherwise we call the run() function:

Example usage:

const running = true;
(running === true) ? stop() : run()
