Issue with misspelled first word and last word without a space or period.

[hjasti]

There is an issue with the regex that is used to identify the misspelled words. The regex is written in a way that every word should have a leading and trailing space. Hence, It is unable to identify misspelled first word(as it will not have a space before it) and last word with out space or period.

My bad... Should have checked the previous issues.
This regex fixed everything.
var regExp = '';
regExp += '(^|[^' + letterChars + '])';
regExp += '(' + incorrectWords.join('|') + ')';
regExp += '(?=[^' + letterChars + ']|$)';
