Benchmark: typeof vs cached typeof

Script Preparation code:

var arr = [null,true,123,'',{},[]];

Tests:

uncached typeof
for(let n = 0; n < 100; n++) { arr.map((i) => { if (typeof i !== 'XXX') { return typeof i; } }); }
cached typeof
for(let n = 0; n < 100; n++) { arr.map((i) => { const typeOfI = typeof i; if (typeOfI !== 'XXX') { return typeOfI; } }); }
