There is already a javascript built-in Array method doing exactly what you need: Array.find

[sharunspi]

Array.find will return the value if the value is found on the list of items in an array. will return undefined if the value didn't found.
We need to returntrue arefalse.

[].includes(item) does the job. Alternatively you can use Array.prototype.find with double negation !![].find(item).

Thanks for the replay !!Array.find(item=>item == elemnt)
