The following example shows how to use two ternary operators in the same expression: let speed = 90 Let canChange = locked != 1 Code language: JavaScript ( javascript ) 3) Using multiple JavaScript ternary operators example In this case, you can simplify it by using a Boolean expression as follows: let locked = 1 If the locked is 1, then the canChange variable is set to false, otherwise, it is set to true.
