Benchmark: Unique Instance Test

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const N = 1<<16;

const getInt = (()=>{r=Math.random;f=Math.floor;return (a=0,b=0x100000000)=>f(r()*(b-a))+a})();
const getStr = (()=>{
    const f = (n)=> n < 10 ? 0x30 + n : n < 36 ? 0x41 + (n - 10) : 0x61 + (n - 36);
    return (n)=> String.fromCharCode(...(new Int32Array(n)).map(()=>f(getInt(0,62)))); 
})();

const createInstance = (str)=>{ return { str, val : getInt() }; }

Tests:

Standard Instance
let list = new Array(N); const getInstance = (value)=>createInstance(value) for(i=0;i<N;i++) list[i] = getInstance(getStr(1));
Unique Instance by key
let list = new Array(N); let refs = {}; const getInstance = (value)=>{ if(refs[value]) return refs[value]; return refs[value] = createInstance(value); } for(i=0;i<N;i++) list[i] = getInstance(getStr(1));
