It was better to use forEach () In general for higher level code where clarity and safety are greater concerns, I previously recommended using Array::forEach as your default pattern for looping (although these days I prefer to use for..of). Reasons to prefer forEach over a reverse loop are: It is clearer to read.
The forEach method was introduced with lineage to the prototypal inheritance of Array object! Needless to say, the forEach clause works only with those data structure which are Arrays.
Therefore, you're creating a quick way to call the forEach function, and you're changing this from the empty array to a list of all tags, and for each in-order, you are calling the function provided. EDIT Logical Conclusion / Cleanup Below, there's a link to an article suggesting that we scrap attempts at functional programming, and stick to manual, inline looping, every time, because ...
The forEach native Javascript function is basically a function that has a loop inside it and will use an iterator function (callback) to execute over each item inside the collection (the collection may be an array or an object).
The list.ForEach could be faster due to using that internally and a for loop without the wrapper would be even faster. I disagree that the list.ForEach(delegate) version is "more functional" in any significant way. It does pass a function to a function, but there's no big difference in the outcome or program organisation.
I can't help but feel that this isn't the best way to wait for a .forEach() to finish. What is the best way to do this?
