Checks if a word exists in a language. Currently supports 10 languages. Uses tries to get very fast results.

$ npm install is-word

var isWord = require('is-word');
var englishWords = isWord('american-english');

console.log(englishWords.check('direction')); // true
console.log(englishWords.check('asddsaaaa')); // false

isWord() returns an object having a trie of the configured language. The object has check method which returns a boolean value if a word is present in a language or not.

To change the languages,

american-english - isWord('american-english');

brazilian - isWord('brazilian');

british-english - isWord('british-english');

french - isWord('french');

italian - isWord('italian');

ngerman - isWord('ngerman');

ogerman - isWord('ogerman');

portuguese - isWord('portuguese');

spanish - isWord('spanish');

swiss - isWord('swiss');

is-word is very fast compared to existing checkers which use a regex for all available words. is-word uses tries data structure which causes comparisons to be done very quickly. Trie creation takes some time but if there are a lot of words to be checked then is-word is way ahead than others.

is-word was initially created for testing inconsistencies and mistakes in translations but can be expanded to much more. So if you have any feature suggestions feel free to open a PR.

Though I have tested the code against a lot of test cases, still if you find a bug, feel free to raise an issue.
