Question

I am going to make a game in javascript , in which i will gives user a option to select given characters and make a valid english word , now the question is that how can i check in javascript that what user enters is a valid english word or not , suppose
i give user following letters

1. O
2. D
3. O
4. G

Now possibly he can make three words from these characters God, Good or Dog .

Thanks in advance

EDIT

what about this guys

Typo.JS

Is this a good way to do so or not ?

Answer 1

He could also conceivably write DO and GO. You need to use a dictionary of the allowed words, and check the answer against that.

var allowedWords = ['god','good','dog','do','go'];
var enteredWord = 'GOD';

if(allowedWords.indexOf(enteredWord.toLowerCase()) >= 0) {
   // match
}
