@DevangPatil 5 лет назад

you can use reduceRight for finding and comparing palindrom (reverse string) strings.

@Techsithtube 5 лет назад

That is a great application . Thanks for sharing.

@liyan542 4 года назад

function palindrome(s) { let reversed = s.split('').reduceRight((a,v) => a + v); return s === reversed; } Yes, I tested It works :)

@ashishaggarwal1842 4 года назад

@@liyan542 how would this perform against reversing string using s.split('').reverse().join('') ? Like which is better ?

@ajantikaa 2 года назад

Palindrome was always possible with reduce. Check this let str = "An apple a day" const revStr = str.split("").reduce((c , v)=> v+c ); console.log(revStr);

All your videos are great, they open up so many more avenues and tools for us kids to get a handle on JavaScript! Thanks!

@K3dev 5 лет назад

Thanks, the flat and flatmap are really useful for WebGL, that way you can keep the buffers organized, with flat you can keep your vertex positions in groups of xyz [[1,0,1], [1,0,-1]] and with flatmap you can keep the other vertex attributes in separated arrays for example your UVs in another array and just join it with flatmap instead of keeping a long unidimensional array with all these values mixed. Thanks again, I didn't know about these methods.

using spread operator var matrix = [[1,2,3],[4,5,6]]; console.log([...matrix[0], ...matrix[1]]); //output: [1, 2, 3, 4, 5, 6]

After watching your video I started to think that you should consider doing a tutorial about RxJS. You have gift for explaining complicated things.

@Techsithtube 5 лет назад

I will consider it. RxJS can be tough to explain . let me break it down the concept .

@AsimZaidiH 5 лет назад

Hm I didn't feel like the copyWithin explanation was strong, still super confused about its behavior.

@NeoCoding 5 лет назад

copyWithin is scary! I hope would never use it))

Yes, Its kind of weird but i heard its used in nodejs a lot.
