Hey Dmitri !
Here is one close to the Array.includes() one ;)

Sometime when we wanted to search an element inside an array we used the following pattern :
const needle = haystack.filter(hay => hay === 'needle')[0];
Now we can use the way more semantic :
const needle = haystack.find(hay => hay === 'needle')

What do you think?

Hey Xavier,
Nice catch! The hack haystack.filter(matchFun)[0] is solved using haystack.find(matchFun) nicely.
Methods like .find() in array should have been created in the first JavaScript versions, but not after 20 years :). Better late than never anyway.
Thanks!

Think I've reread many of your articles at least twice in the last two years while learning Javascript, React, etc. Thanks for sharing your knowledge, has made the path to becoming a modern day developer easier!
