Syntax
console.log(3 > 2)
console.log(3 < 2)
Strings can also be compared
console.log("Aardvark" < "Zoroaster")
Uppercase characters are always less than lower case characters, so "Z" < "a". Non alphabetic characters are less than alphabetic characters
console.log("Zebra" < "aardvark")
console.log("!" < "aardvark")
console.log("!" < "Zebra")
console.log("3" < "Zebra")
console.log("!" < "3")
Empty values
There are two special empty values, null & undefined that denote the absence of any meaningful value. They can be used interchangeably and are an accident of JavaScripts design.
console.log(null == undefined);
