Javascript is a non-opinionated language and allows you to do an operation in many ways. This repository tries to find which approach is faster in a range of different systems.

Options:
-h, --help output usage information
-V, --version output the version number
-p, --path [path] Path to output the results to

Your benchmark results will be appended to the result set.
$ node-benchmarks --dryrun
typeof x 22,545,486 ops/sec ±11.66% (30 runs sampled)
constructor check x 18,023,021 ops/sec ±9.23% (27 runs sampled)
Fastest is typeof
[1/22] type_check
buffer x 10,889 ops/sec ±15.81% (28 runs sampled)
string+ x 53,569 ops/sec ±21.72% (27 runs sampled)
Fastest is string+
[2/22] manip_recv_buf
filterDuplicates x 17,466 ops/sec ±7.64% (26 runs sampled)
eliminateDuplicates x 19,910 ops/sec ±7.11% (28 runs sampled)
Fastest is eliminateDuplicates
When --dryrun is used, no files are generated and the results are shown on the console.
You can find the result sets here. I recommend you fork and send a pull requests to add your results to this list.
