Filter Javascript Slow at Garrett Kirk blog

Filter Javascript Slow. Filter has all the caveats of some, but it will always iterate over the entire array instead of halting at a single element. This code randomly fills an array of a given size with integers between 0 and 999 inclusive and runs three different functions which should filter only the even numbers: Javascript arrays are great when you only have a few items, but when you have a large amount of data or want to do complex. This is very slow, it takes 1 second to iterate over 100 items from my products array. I tried the same using asyc.each, but get the. The filter() method of array instances creates a shallow copy of a portion of a given array, filtered down to just the elements. The filter method is so clean, but it means that we’ve got to loop through every item in the array at least once. All the results clearly show that for loop are more proficient than for each than map/reduce/filter/find. To be precise, the filter method is 77% slower than for loop.
