//3.if statement operator
//4.right side of if statement
//5.shorthand then operator
//6.if true the result will be "passed"
//7.shorthand else operator

Example 2: ternary operator shorthand javascript

let startingNum = startingNum ? otherNum : 1
// can be expressed as
let startingNum = otherNum || 1

// Another scenario not covered here is if you want the value 
// to return false when not matched. 
//The JavaScript shorthandfor this is:
let startingNum = startingNum ? otherNum : 0
// But it can be expressed as
let startingNum = startingNum && otherNum
