There is nothing wrong with using new Array() to construct array of known capacity. By default, I think JS literal arrays will have a capacity of 4, so especially if you know you will have less than four elements, or a non power of two number of elements, this can be seen as a micro-optimization. `bluebird` uses new Array() extensively, e.g. https://github.com/petkaantonov/bluebird/blob/12154adb5016609901550aad5250045670644dd4/src/util.js#L73 https://github.com/petkaantonov/bluebird/blob/12154adb501660...
