Benchmark: Compare lodash isEmpty and length comparison on arrays

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 = ['a', 'b', 'c', 'd', 'e'];

// array of objects
window.foo3 = [{ 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);
length empty array
window.foo1.length === 0;
isEmpty array of strings
_.isEmpty(window.foo2);
length array of strings
window.foo2.length === 0;
isEmpty array of objects
_.isEmpty(window.foo3);
length array of objects
window.foo3.length === 0;
