Benchmark: spread array performance (vs slice, splice, concat, filter)

Tests:

Splice
const testArray = [1, 2, 3, 4, 5, 6, 7, 8, 9]; const newTestArray = testArray.splice(testArray.indexOf(6),1);
Slice
const testArray = [1, 2, 3, 4, 5, 6, 7, 8, 9]; const newTestArray = [...testArray.slice(0,testArray.indexOf(6)),...testArray.slice(testArray.indexOf(6)+1)];
Concat
const testArray = [1, 2, 3, 4, 5, 6, 7, 8, 9]; const newTestArray = testArray.slice(0,testArray.indexOf(6)).concat(testArray.slice(testArray.indexOf(6)+1));
For
const testArray = [1, 2, 3, 4, 5, 6, 7, 8, 9]; const newTestArray = testArray.filter((item) => { if (item !== 6){ return item } });
