4:45 BTW, I remember seeing on a JavaScript video that it's bad practice to use array notation to get a particular character from a string like you've done here with "n[0]". I don't remember the details of why it's bad. But it was suggested that it's better to use one of the string functions like n.slice(0,1) or n.charAt(0).

I don't understand why you don't have a lot more subscribers. I have went through several videos and found them very useful .

Wow! This really takes away the mystique of higher order functions for me after years of programming in TS. How they work is obvious to me now, hence this video did its job. I just never really gripped how functions sent in as arguments run the code for each element in a collection, but now seeing you write these higher order functions, I see how they do the processing in a black box just like they would for any other primitive argument type. Thank you!

I've run into many tutorials describing what callbacks are but don't go into the specifics of why it's needed. I've always struggled to find the value of a callback; for instance, why do functions like setTimeout(), array methods, addEventListeners, need a function as a parameter instead of using primitive types to tell it what to do? Thanks so much for explaining this. Cheers!

Hi Sina, thank you for the lessons. I have benefited a lot from you. I have a question regarding SetTimeout()،Is it possible to change the display duration of a function from time to function so that it is displayed after initializing and executing the first function? Example : setTimeout(function(),2000); to: setTimeout(function2(),function1()); I hope you get the idea،Thank you, Sina.

I don’t understand most usages of higher order functions. Would love some help! There are separate issues. The example at 8:50 with a function that returns a function does not make sense at all. Why not just create a function that does the thing while taking in that parameter? What do you gain out of writing a function that returns an anonymous function that does the work instead of writing a function that does the thing in the first place? The issue I have with map and filter and the rest is separate. In specific usages they’re great. I see them chained often and this drives me crazy because of the inefficiency. Each loops over every element. Each creates a separate array which itself takes time and space. Instead of chaining multiple together (which seems to be common) I don’t understand why people don’t use a single loop with the logic so you only iterate over each element once and only need to create a single array to return in the process. For usages where you only use one or can only possibly iterate over a small number the inefficiency seems trivial. I’ve seen this done over tens of thousands of items and on a backend writing something twice as efficient feels like the way to go cutting down on database drag. Chaining multiple together feels like writing several separate loops each creating a bunch of data that only gets used to write another loop to create more data to write another loop …. Or you could write a single loop! Instead of taking in a function as a parameter, why not use scope to gain access to a function? What is the benefit to doing it this other way? This seems common with callbacks. Most of the time it seems more direct to just write the functionality so it’s available in scope.

That's great, also the quality is really high, even only the into can make u click the subscribe button.

With the makeClickHandler function, why return a function? Why not just have document.body.style.fontSize within makeClickHandler on its own? I'm sure there's a reason but I'm not able to see it at the moment.
