There is not even a link to the source code on the npm page for it. I installed it and inspected the source code, but I doubt everyone does this when installing a dependency.
``` exports = module.exports = trim;
function trim(str){ return str.replace(/^\s|\s$/g, ''); }
exports.left = function(str){ return str.replace(/^\s/, ''); };
exports.right = function(str){ return str.replace(/\s$/, ''); };
```
