For C# developers, who know LINQ:

filter == Where()
map == Select()
find == FirstOrDefault()
some == Any()
every == All()
reduce == Aggregate()
includes == Contains()

you're welcome.

@EduBasabe

This is the most simple, short, good quality and well explained tutorial I have ever seen.

@hosseinpanahy5358

This video is one of the reasons that I preach people learning sth in this era wouldn't require taking particular courses and having high-paid pedagogues... THANKS SIR♥️♥️♥️♥️♥️♥️

@davidalexander8786

U can use reduce to consume an array of promises step by step


await [1, 2, 3, 4].reduce(async (prevPromise, nextValue) => {
        await prevPromise;
        return new Promise((resolve, reject) => {
            setTimeout(() => {
                console.log('nextValue', nextValue)
                resolve()
            }, 200)
        })
    }, Promise.resolve())

How is it that I read so many array methods articles and couldn't wrap my head around them, but when I watched this video everything made perfect sense? You're amazing, thank you for making these tutorials!

@robertofrz

5 years later, and still this is the best teacher on youtube! Thanks man, you're awesome!

@irenazlo5173

This tutorial has more knowledge than many 1hour+ tutorial videos. Well done!

@liorocker1

Wow, the best 10 minutes used to learn how to deal with arrays, Thanks a lot :)

@johnnyholiday1150

@true_visual

No fluff, straight to the point! I really thank you for this video!

@cswalker21

Hello, I'm getting back into web development after a 20+ year absence, and it's pretty scary because everything is so different! Your channel has been a big help. Thank you so much for your clear explanations and tight presentation. Very valuable!

@aakash-codes

Can't believe I just learned about all these methods under a 10 min tutorial. Man love & respect for you. 🙇‍♂🙇‍♂

@joohimks

This video will deliver the expectations you expect from the title. Simple and straightforward

@phil8899

When learning Javascript you start to learn 10 percent then.... 5 years later you finish with the last 20 percent of knowledge.. Good stuff mate

@SportsJames82

Funny how much more helpfully and clear this is about these methods over some tutorials that spend 30 to 45 on each method

@vladstankovic1050

No bullshit, just pure explanation. Awesome!

@kiokoc0d3s
