I need to convert strings to some form of hash. Is this possible in JavaScript?
I'm not utilizing a server-side language so I can't do it that way.

In order to create a unique hash from a specific string, it can be implemented using their own string to hash converting function. It will return the hash equivalent of a string. Also, a library named Crypto can be used to generate various types of hashes like SHA1, MD5, SHA256 and many more.
You can implement a Hash Table in JavaScript in three steps: Create a HashTable class with table and size initial properties. Add a hash() function to transform keys into indices. Add the set() and get() methods for adding and retrieving key/value pairs from the table.
Definition of JavaScript hash() Hash function in Javascript is any function that takes input as arbitrary size data and produces output as fixed-size data. Normally, the returned value of the hash function is called hash code, hash, or hash value.
String.prototype.hashCode = function() { var hash = 0, i, chr; if (this.length === 0) return hash; for (i = 0; i < this.length; i++) { chr = this.charCodeAt(i); hash = ((hash << 5) - hash) + chr; hash |= 0; // Convert to 32bit integer } return hash; }; Source: http://werxltd.com/wp/2010/05/13/javascript-implementation-of-javas-string-hashcode-method/
