versus v0.2.0

versus.js

Compare two variables with the comparison operator specified as a string.

(This is really just a silly-simple switch-case abstracted into a reusable module.)

Usage

versus(1, '==' , 2); //=> false
versus(1, '===', 2); //=> false
versus(1, '!=' , 2); //=> true
versus(1, '!==', 2); //=> true
versus(1, '<'  , 2); //=> true
versus(1, '>'  , 2); //=> false
versus(1, '<=' , 2); //=> true
versus(1, '>=' , 2); //=> false

Versus uses deep-equal for the == and != comparisons. So we can do:

versus({ foo: 1 }, '==', { foo: 1 }); //=> true
versus({ foo: 1 }, '!=', { foo: 1 }); //=> false

Read the tests.

API
