Tests:

  • Array.find, 3 elements

     
    const target = getRandomInt(2);
    array_small.find(el => el.id === target);

  • Map.get, 3 elements

     
    const target = getRandomInt(2);
    map_small.get(target);

  • Array.find, 10 elements

     
    const target = getRandomInt(9);
    array_large.find(el => el.id === target);

  • Map.get, 10 elements

     
    const target = getRandomInt(9);
    map_large.get(target)

  • Clone array 3

     
    const array = cloneArray(array_small);

  • Clone map 3

     
    const map = cloneMap(map_small);

  • Clone array 10

     
    const array = cloneArray(array_large);

  • Clone map 10

     
    const map = cloneMap(map_large);
