**1. Typo** - line 34: I think `// for tokenization` or `// for tokenizing` is better than `// for tokenize`. - line 53: I don't get what `// For use in libraries implementing .is()` means. Which libraries? - line 58: `// concern matchs` should be `// concern matches` - line 174: need to change `charactor` to `character`. **2. Coding rule** - line 372: `results= []` --> `results = []`, `var fn` --> `var fn` (tab to space) - General: I see there's no coding rule for anonymous function. You need to choose one of `function()` or `function ()`.
