Javascript Array Filter Vs For Loop Performance at Max Ewing blog

Javascript Array Filter Vs For Loop Performance. One reason could be that for. 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: The for.of loop is slightly ahead of the rest, but the difference is not significant. Myarray.foreach((item) => { total += item }) the tests were run with node js v18.17.0. Which code has a better performance (or is preferable for other reasons) among the following two cases? For (const item of myarray) { total += item } array.foreach. 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. To be precise, the filter method is 77% slower than for loop. Filter has all the caveats of some, but it will always iterate over the entire array instead of halting at a single element. I compared the running times of five very common ways ( map, foreach, for, while, do while) of looping through an array using an array of 100 values and another array of 10.
