Serializing json vs. using 2 keys in localStorage

Benchmark created on

Description

The goal is to figure out if it's faster to serialize a simple object to json or use two keys in the storage.

We assume that we know exactly how the object has to be (de)serialized.

For that we serialize and unserialize the same object into localStorage. Once using two separated key and in the other case using JSON.

Setup

var toSerialize = {
      foo: 'bar',
      bar: 'foo'
    };
    var unSerialized;

Teardown


    localStorage.clear();
    delete unSerialized;

Test runner

Ready to run.

localStorage using two keys
localStorage.setItem('foo', toSerialize.foo);
localStorage.setItem('bar', toSerialize.bar);
unSerialized = {
    foo: localStorage.getItem('foo'),
    bar: localStorage.getItem('bar')
};
 
ready
localStorage with JSON
localStorage.setItem('serialized', JSON.stringify(toSerialize));
unSerialized = JSON.parse(localStorage.getItem('serialized'));
ready
