Script Preparation code:

var arr = [1,2,3,4,5,6,7,8,9,0], farr;

Tests:

Filter
farr = arr.filter((item) => { return (item>4); });
For Loop
for (let i=0,len=arr.length;i<len;i++) { if (arr[i]<5) continue; farr.push(arr[i]); }
For Loop 2
for (let i=0,len=arr.length;i<len;i++) { if (arr[i]>4) farr.push(arr[i]); }
For In
for (var i in arr) { if (arr[i]>4) farr.push(arr[i]); }
Reduce
farr = arr.reduce((a, val) => { if (val > 4) a.push(val); return a; }, []);
