Let's say I have two strings, is there any way to check if they are at least 90% similar?
var string1 = "theBoardmeetstoday,tomorrow51";
var string2 = "Board meets today, tomorrow";
Thanks,
Tegan

To compare two strings in JavaScript, use the localeCompare() method. The method returns 0 if both the strings are equal, -1 if string 1 is sorted before string 2 and 1 if string 2 is sorted before string 1.
You can check the equality of two Strings in Java using the equals() method. This method compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object.
You should not use == (equality operator) to compare these strings because they compare the reference of the string, i.e. whether they are the same object or not. On the other hand, equals() method compares whether the value of the strings is equal, and not the object itself.
The strict equality operator ( === ) checks whether its two operands are equal, returning a Boolean result. Unlike the equality operator, the strict equality operator always considers operands of different types to be different.
The wikipedia entry for Levenshtein distance includes a sample implementation.

jsdifflib is a JavaScript port of Python's excellent difflib library.
It has a function ratio() which "return[s] a measure of the sequences’ similarity as a float in the range [0, 1]."
