Comparison

There's another set of operators that all return a Boolean value as a result of the operation. These are the comparison operators. The following table lists them together with example uses:

Operator symbol	Description	Example
==	Equality comparison: Returns true when both operands are equal. The operands are converted to the same type before being compared. Also called loose comparison.	> 1 == 1; true > 1 == 2; false > 1 == '1'; true
===	Equality and type comparison: Returns true if both operands are equal and of the same type. It's better and safer to compare this way because there's no behind-the-scenes type conversions. It is also called strict comparison.	> 1 === '1'; false > 1 === 1; true
!=	Non-equality ...
