Are these lines of JavaScript code equivalent?

No, they AREN’T NECESSARILY EQUAL always if b is a getter that updates a variable. It’s bad practice to code this way though

var log = 0;
var a = {
    get b() {
        log++;
        return log;
    }
}

var c = (a.b !== null) ? a.b : null;
// outputs 2
console.log(c);

var log = 0;
var a = {
    get b() {
        log++;
        return log;
    }
}

var c = a.b;
// outputs 1
console.log(c);
