See TimDown s jshashtable suggestion below This example is confusing because you re using foo and bar as both key and value in two instances Much clearer to show that var dict dict key1 val1 dict key2 val2 dict s key1 element can be referenced equivalently by both dict key1 and dict key1 How To Do Associative Array hashing In JavaScript. A hashing function is just a way to translate something into a numeric representation There is no one singular good hash function e g SHA 256 BSD checksum Rabin fingerprint but what matters is that it s cheap to calculate and it s evenly distributed The number from that function can then be used as the index in an array An example of how to generate an hexadecimal based hash encoding for each algorithm var str Sample text console log MD5 MD5 hex str console log SHA1 SHA1 hex str console log SHA256 SHA256 hex str console log SHA512 SHA512 hex str console log RIPEMD 160 RMD160 hex str Browsers
