Benchmark: Some vs. Filter vs. indexOf vs. Includes vs. Find - nested#223423

Script Preparation code:

var array = [];
for (var i = 0; i < 10000; i++) {
  const obj = {
    data: {
      bool: !!Math.floor(Math.random() * 100 > 75)
    },
    str: Math.floor(Math.random() * 100)
  };
  array.push(obj);
  array.push({...obj, str: obj.str + 1 });
}

Tests:

Array.filter
var tempResult = array.filter(({ data, str }) => { const shouldBeTrue = data.bool; const isSmall = str < 1; return shouldBeTrue && isSmall; });
Array.find
var tempResult = array.find(({ data, str }) => { const shouldBeTrue = data.bool; const isSmall = str < 1; return shouldBeTrue && isSmall; });
Array.includes
var tempResult = array.includes(({ data, str }) => { const shouldBeTrue = data.bool; const isSmall = str < 1; return shouldBeTrue && isSmall; });
Array.reduce
var tempResult = array.reduce((found, { data, str }) => { const shouldBeTrue = data.bool; const isSmall = str < 1; if(shouldBeTrue && isSmall) { return { count: found.count + 1 }; } else { return found; } }, { found: 0 });
for
var tempResult = []; for (var i = 0; i < array.length; i++) { const {data, str} = array[i]; const shouldBeTrue = data.bool; const isSmall = str < 1; if(shouldBeTrue && isSmall) { tempResult.push(array[i]); } }
