Relational operators are used in relational expressions and always yield a Boolean result.
Although generally considered to be member of the relational operator set, equality and non-equality tests are classified as equality operators in the ECMA standard.
The following table lists all operators that could be loosely classified or specifically classified as relational operators:
| Operator | Description |
|---|---|
| == | Equal to |
| === | Identically equal to |
| != | NOT equal to |
| !== | NOT identically equal to |
| < | Less than |
| <= | Less than or equal to |
| > | Greater than |
| >= | Greater than or equal to |
It follows that all equality operators are generally classifiable as relational operators and all relational operators are members of the set of logical operators, since they all yield a Boolean value as a result.
