Ternary operators with disjunction?

Question

Is it possible to add disjunction in condition? I want to add an empty string besides null.

Answer 1

Yes it's entirely possible to combine multiple conditions with conditional operator.

However in this case only 1 condition is suffice to test for null or empty string as both evaluates to falsy in JavaScript.

Hence,
name ? name : 'Anonymous'

P/S: When in doubt next time, you may experiment it by yourself. 😉

Answer 2

For multiple disjunction, check out this challenge I did:

To calculate interest based on different amount input range:

function interest(a) {
return a>90000? a*0.05:
a>50000? a*0.04:
a>20000? a*0.03:
a>5000? a*0.02:0;
}
