Apply an array of arguments... faster


Apply an array of arguments... faster.

var fastApply = require('fast-apply')
  , scope = {}
function run() {}
fastApply(run, scope, [ 'a', 'b', 'c' ]);
$ npm install fast-apply


It uses a simple switch statement to call the function rather than apply for up to 5 arguments.

While more than 5 arguments would run faster using apply, anything less will be up to twice as fast

If the scope is null, fastApply will run up to 3 times faster than apply

  • It is only optimized for 5 arguments or less. If you think the function will frequently be taking more than 5 arguments, I suggest that you instead use apply
