In this test we compared the following object clone lib speeds:
- @logicamente.info/clone (https://github.com/logicamenteinfo/clone)
- clone (https://github.com/pvorb/clone)
- deepcopy (https://github.com/sasaplus1/deepcopy.js)
- object-copy (https://github.com/jonschlinkert/object-copy)
- native JSON.parse(JSON.stringify)
You can see it running in this video.
- A common object to be cloned on every lib
{
literal: 1,
array: [1],
objects: [{ literal: 1 }, { literal: 1 }],
child: {
literal: 1,
array: [1],
objects: [{ literal: 1 }, { literal: 1 }],
},
}
// This object uses 206 bytes in order to be instanced-
Run the full test a few times (set to 10 tests)
-
Run a large number of iterations for each full test (set to 1.000.000 iterations/test)
-
Register the time taken in every full test, then calculate the average
As the object will be cloned to another location in memory, it will generates an I/O throughput of 196.46 MB for each full test (206 B x 10^6), that results in 1.92 GB per lib (206 B x 10^7).
The average time to run this scenario is plotted below:
