Relational	>, >=, <, <=
Equality	==, !=
Conditional And	&&
Conditional Or	||
Ternary	[[?:
Assign	=, +=, -=, *=, /=, %=, [[|>

Equality

These are the rules the equality operators (==, !=) follow:

1. Values of different types will never be equal.
2. number and string types of the same value will always be equal.
3. object, array, and function types will only be equal if they refer to the same instance, not value.
4. true, false, null, and undefined are only equal with themselves.

Relational

The relational operators (>, >=, <, <=) can only be used on number and string values. When used on string values the result allows you to determine sort order.
