Basic Algorithm Scripting - Finders Keepers

[bakerandrew4]

Tell us what’s happening:
Can someone help me find a resource that explains the "=== 0’ at the end of the arrow function?

I understand it makes the function return a true or false but I can’t seem to find what thats called

  **Your code so far**

function findElement(arr, func) {
let num = arr.find(func);
return num;
}

//findElement([1, 2, 3, 4], num => num % 2 === 0);

let func = (num) => num % 2;

@bakerandrew4

num % 2 === 0

Hi.
This whole thing is a condition, check for equality. This particular expression will be true if num is divisible by 2 without a remainder

If you want more examples, I suggest to look into methods like:
filter()
every()
some()

There are bunch of similar expressions, in the examples of code with this methods.
