Benchmark: Boolean vs String comparison for discriminated unions

Script Preparation code:

function getRandoBoolean() {
  return !!(Math.floor(Math.random() * 2));
}

function getRandoString() {
  return !!(Math.floor(Math.random() * 2)) ? 'accepted' : 'rejected';
}

function getRandoShortString() {
  return !!(Math.floor(Math.random() * 2)) ? 'y' : '';
}


var arrB = [...(new Array(1000))].map(v => getRandoBoolean());
var arrStr = [...(new Array(1000))].map(v => getRandoString());
var arrShortStr = [...(new Array(1000))].map(v => getRandoShortString());

var arrObjB = [...(new Array(1000))].map(v => getRandoBoolean() ? {ok : true ,b: 'value'}: {ok : false ,c: 'value'});
var arrObjStr = [...(new Array(1000))].map(v => getRandoBoolean() ? {ok : 'yes' ,b: 'value'}: {ok : 'no' ,c: 'value'});
var arrObjProp = [...(new Array(1000))].map(v => getRandoBoolean() ? {ok : true ,b: 'value'}: { c: 'value'});

Tests:

rB
const rB = arrB.reduce((acc, v) => v ? acc + 'yes' : acc + 'no', '');
rBStrict
const rBStrict = arrB.reduce((acc, v) => v === true ? acc + 'yes' : acc + 'no', '');
rStr
const rStr = arrStr.reduce((acc, v) => v === 'accepted' ? acc + 'yes' : acc + 'no', '');
rShortStr
const rShortStr = arrShortStr.reduce((acc, v) => v ? acc + 'yes' : acc + 'no', '_');
rObjB
const rObjB = arrObjB.reduce((acc, v) => v.ok ? acc + 'yes' : acc + 'no', '');
rObjBStrict
const rObjBStrict = arrObjB.reduce((acc, v) => v.ok === true ? acc + 'yes' : acc + 'no', '');
rObjStr
const rObjStr = arrObjStr.reduce((acc, v) => v.ok === 'yes' ? acc + 'yes' : acc + 'no', '');
rObjProp
const rObjProp = arrObjProp.reduce((acc, v) => v.ok ? acc + 'yes' : acc + 'no', '');
rObjPropIn
const rObjPropIn = arrObjProp.reduce((acc, v) => 'ok' in v? acc + 'yes' : acc + 'no', '');
