Try to improve using Math.hypot

Just this line will work as a solution

| if(el > 0){ | ||
| arrPos.push(el) | ||
| } | ||
| }); | ||

Please, use Array.prototype.filter method here

Redundant condition. Just if (el) { will work
Please, see https://javascript.info/logical-operators
| let newArr = arr.reverse(); | ||
| if (arr.length > 3) { | ||
| newArr.length = 3; | ||
| } | ||
| return newArr; |

If test cases had unsorted array, it woudn't work.
To prevent errors in case tests will reworked, please add sort method in place of reverse

if (!el) will work
Please, see https://javascript.info/logical-operators
| let newArr = []; | ||
| arr.map((el) =>{ | ||
| let i = newArr.find(item => item === el); | ||
| if (i === undefined){ |

!newArr.includes(el) will work. And remove line with find
|
And try to resolve conflicting files. It's very significant in real project |
