Ternary Expressions in JavaScript

let memberType = 'basic';
let price = memberType === 'basic' ? 5 : 10;

In the example, the condition that is evaluated is whether memberType === 'basic'. 
If this condition is true, then price will be 5, and otherwise it will be 10. 
The equivalent long-hand conditional expression would be:

let memberType = 'basic';
let price;

if (memberType === 'basic') {
  price = 5;
} else {
  price = 10;
}

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

ternary operator javascript

function fee(isMember)
{
return isMember==true?"$20":"$100"
}

console.log(fee(true))

/*a==b?c:d*/
/*the syntax is check if a equals b, if so, return c otherwise return d*/
/*1==1?4:10: check if 1 equals 1, if so, return 4 otherwise return 10*/
