Benchmark: Compare lodash isEmpty and Set.size

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min.js"></script>

Script Preparation code:

// empty array
window.foo1 = [];

// array of strings
window.foo2 = new Set(['a', 'b', 'c', 'd', 'e']);

// array of objects
window.foo3 = new Set([{ a: 1, b: 2, c: { a: 1, b: 2, c: { a: 1, b: 2 } } }, { a: 1, b: 2, c: { a: 1, b: 2, c: { a: 1, b: 2 } } }, { a: 1, b: 2, c: { a: 1, b: 2, c: { a: 1, b: 2 } } }]);

Tests:

isEmpty empty array
_.isEmpty(window.foo1);
size empty array
window.foo1.size === 0;
isEmpty array of strings
_.isEmpty(window.foo2);
size array of strings
window.foo2.size === 0;
isEmpty array of objects
_.isEmpty(window.foo3);
size array of objects
window.foo3.size === 0;
