I guess it's kind of off topic but does anybody know a good site to watch new movies online ?

[@titanachilles7627]

@George Michael Lately I have been using FlixZone. Just search on google for it =)

[@markcory215]

@Titan Achilles Definitely, I have been using Flixzone for years myself =)

Can you do something on how to get odd and even numbers using arrays

[@codewithbubb]

Sure, i'll put something together.

[@Girlgirls12233]

i don't understand why - i? and not just[ inStr.length - 1 ]

[@kremowydzien]

I didn't think by myself about turn to lower case and removing the non-alphanumerical characters. I did it after watching the video. I used this solution: const isPalyndrome = (str) => { str = str.replace(/[^a-z]/gi, "").toLowerCase(); const reverse = str.split("").reverse().join("").toLowerCase(); return str === reverse; }

[@codewithbubb]

Yep, good practice to lower case everything to make sure it matches. I like the Regex to remove the non-alpha characters (could also use \W to match non-alphanumeric too 😉).

[@EduardoOviedoBlanco]

I think your first solution was better than the second one

[@blurrywaters]

Could someone explain the inStr[inStr.length - 1 - i] I’m confused on this.

[@Stancehall]

You still need help?

[@blurrywaters]

@@Stancehall if you could explain the statement above yes that’s be very helpful, thanks!

[@selchukkarakus6169]

This code doesn't work with strings containing - (hyphen)or _ (underscore) eg "_eye" or "0_0 (: /-\ :) 0-0" ?

[@codewithbubb]

Yeah, the \W word boundary won't pick these up and remove them (I would consider hypens to be part of words but not sure about underscores?). You can adjust your regex to suit your requirements / rules of what should be considered part of the palindrome. e.g /[^a-z]/gi will remove anything that's not actually a letter. Hope that helps?

[@uaplatformacomua]

So hard I got the issue

[@velmurugan.personel]

Why not use this i++ instead of i+=1 and inStr[inStr.length - 1] instead of this inStr[inStr.length - 1 -i ]

[@codewithbubb]

Yes, i++ is fine however it's discouraged in a lot of JavaScript style guides (like AirBnB) so ES Lint complains about it. I've just got in to the habit of using that format now!

[@velmurugan.personel]

@@codewithbubb Thanks your response man keep rocking.......

[@codewithbubb]

You're welcome! Thanks for your comment also, it's good to question things all the time!
