HTML Preparation code:
<!--your preparation HTML code goes here-->
Script Preparation code:
const o1 = {}; const m = new Map(); const keys = []; for (let i = 0; i < 100; i++) { keys.push('key' + i); } const o2 = {}; for (key of keys) { o2[key] = 0; }
Tests:
non-initialized object
for (let n = 0; n < 50; n++) { for (let i = 0; i < 100; i++) { const key = keys[i]; if (n === 0) { o1[key] = 0; } else { o1[key] += 1; } } }
initialized object
for (let n = 0; n < 50; n++) { for (let i = 0; i < 100; i++) { const key = keys[i]; if (n === 0) { o2[key] = 0; } else { o2[key] += 1; } } }
map
for (let n = 0; n < 50; n++) { for (let i = 0; i < 100; i++) { const key = keys[i]; if (n === 0) { m.set(key, 0); } else { m.set(key, m.get(key) + 1); } } }
