PHP "??" operator in javascript [duplicate]

Question

Easy question. Does exist something like php's ?? in javascript?

In php you can do condition ?? statement2

which is the same as condition? condition : statement2.

Is there something like that in javascript?

Answer 1

I would use the logical or operator (||)

console.log("true value" || "other")
console.log(false || "other")

This works because (source):

expr1 || expr2 Returns expr1 if it can be converted to true; otherwise, returns expr2
