keyval.js BETA

a fast key value pair library

USAGE

// Instantiate keyval.
var kv = new keyval();
// Add 1 million key value pairs.
for (var i = 1; i <= 1000000; i++) {
// 1st arg is the key, second is the value.
kv.set(i.toString(), i);
}
// Delete a key value pair.
kv.del('100000');
// Iterate over the key value pairs.
var tmp, foo;
while (tmp = kv.itr()) {
// Assign the value to foo.
foo = tmp.v;
}
// Rewind the iterator to the first key.
kv.rwd();
// Get the number of key value pairs set.
var length = kv.len;
// Empty the key value pair pool.
kv.empty();

FEATURES

• Iterates key value associated data faster than using a JavaScript object (~10x on Chrome, ~5x on Firefox)
• Finds a specified key in 0ms
• Deletes a specified key in 0ms
• Provides key count in 0ms
• Sets key value associated data a bit slower than using a JavaScript object

Benchmarked using 1 million string keys; with each one of them associated to 1 integer value
Tested on Chrome, Firefox (pending for the rest of the browsers)
