Inline if this then that else this other thing. Handy when you need to do this in a template literal.
// condition ? yep : nope;
let my_variable = condition ? "yep" : "nope";
// Example
let dads_birthday = false;
let str = `Your Dads Birthday: ${ dads_birth_day ? dads_birth_day : "I forgot." }` // ES6
// str would be "I forgot."
