Filtering 1
var users = [ { id: '1', name: 'User 1', rating: 3, properties: [ { name: 'Duplex Flat', neighborhood: 'Friderichshain' }, { name: 'Cozy Apartment', neighborhood: 'Friderichshain' } ] }, { id: '2', name: 'User 2', rating: 2, properties: [{ name: 'Single Room', neighborhood: 'Lichtenberg' }] } ]; users.filter(item => item.id !== '2')
Filtering 2
var users = { 1: { id: '1', name: 'User 1', rating: 3, properties: [ { name: 'Duplex Flat', neighborhood: 'Friderichshain' }, { name: 'Cozy Apartment', neighborhood: 'Friderichshain' } ] }, 2: { id: '2', name: 'User 2', rating: 2, properties: [{ name: 'Single Room', neighborhood: 'Lichtenberg' }] } }; delete users['2']

Autogenerated LLM Summary

, generated one year ago):
Let's break down the provided benchmark definition and individual test cases to understand what is being tested. **Benchmark Definition** The benchmark definition represents a JavaScript function that filters an array of user objects based on a condition. The function takes an array of users as input, where each user object has properties such as `id`, `name`, `rating`, and `properties`. The filter function uses the `Array.prototype.filter()` method to remove users with a specific ID. **Options Compared** The benchmark compares two approaches: 1. **Array.prototype.filter()**: This is a built-in JavaScript method that filters an array based on a provided callback function. 2. **Direct object access**: In this approach, the filter condition uses direct object access (`users['id'] !== '2'`) to check if the user's ID matches the specified value. **Pros and Cons of Each Approach** 1. **Array.prototype.filter()**: * Pros: Efficient, scalable, and widely supported across modern browsers. * Cons: May have slower performance for very large arrays due to the overhead of the `filter()` method. 2. **Direct object access**: * Pros: Can be faster for small arrays or specific use cases where direct object access is optimized by the browser engine. * Cons: May not be as efficient or scalable for larger arrays, and its performance can vary across browsers. **Library** There are no libraries used in this benchmark definition. However, the `Array.prototype.filter()` method is a built-in JavaScript method that is part of the ECMAScript standard. **Special JS Feature/Syntax** None mentioned in this specific benchmark.
