How to know if a javascript array contains any even numbers using some #shorts

------------

[sanujatharinda]

Thank you for videos like this. I learn things instead of wasting time watching shorts

In Python you can use any() function for same purpose.

[abdulamite]

Find and findIndex are also both great array methods. In certain cases these are better than writing your own loops if you just want to find items in a given array

[johnddonnet]

These shorts are great, more about classes and other oop principles

You da 🐐 💯💯.

Please do a DSA course for ES6. Many of the JS DSA courses on this platform are either outdated or use inbuilt functions. For example trunc() and forEach() are inbuilt functions/methods but some of us want to go in depth on how those functions/methods work under the hood from scratch.

This combined with your teaching method would be immensely helpful no 🧢🧢.

Find and checking for null is still more widespread and works well.

does every() have the opposite effect?

[pqsk]

(number & 1) === 0 is more efficient

Love the nice informative short videos ... One question what extension are you using in vscode that's showing the output in JavaScript as you type? Is it quokka or something else?

[oussamaboumaad]

The other function is call all() to check all instances are odd or even

[TheJonathasg]

I always use 'find' for the same purpose.

[leotravel]

This basically does exactly the same as the good old ".find()" but returning "true" instead of the callback result

wow thanks this is new for me, I used to map each element into a boolean that satisfy the condition then use reduce to combine the booleans (a || b) into a single boolean 🤣🤣

[chinmayh]

Its used to break out of the loop when certain condition is met. So it doesn't iterate through remaining elements.

What Extension do you use for real time typing completion suggestion?

[michaelwu]

Is not better use "typeof" to check?

[jacksonbourne]

Which extension is showing those in-line errors?

[seifeldinismail]

What is the thing that updates in real time if it’s an error or not?

[SpaghettiRealm]

I think .filter() is gd for this purpose and it’s readable

[damienspectre]

console.log(arr.filter(x => x % 2 === 0).length > 0);
