Tests:
spread operator
const lane = {origin: {center: [-20, 30]}}; const routes = [{origin: {center: [-10, 40]}}, {origin: {center: [10, 25]}}]; const other = [...routes, lane];
push
const lane = {origin: {center: [-20, 30]}}; const routes = [{origin: {center: [-10, 40]}}, {origin: {center: [10, 25]}}]; var other = routes.push(lane)

Autogenerated LLM Summary
(model
llama3.2:3b
, generated one year ago):
The provided benchmark definition is testing the performance of two different methods to add an object to an array: the ES6 spread operator (`...`) and the traditional `push()` method. **What's being tested:** * The spread operator (`...`): It takes elements from an array or object and spreads them out into a new array, creating a shallow copy. * The traditional `push()` method: It adds one or more elements to the end of an array. **Options compared:** * Two different methods are being compared: + Spread operator (`...`) + Traditional `push()` method **Pros and Cons of each approach:** * **Spread Operator (`...`):** + Pros: - More readable and concise code - Creates a new array, which can be beneficial for performance-critical applications + Cons: - May incur additional overhead due to the creation of a new array - Can lead to slower execution times for very large arrays * **Traditional `push()` method:** + Pros: - Generally faster and more efficient, especially for large arrays - Does not create a new array, which can be beneficial for performance-critical applications + Cons: - May lead to less readable code due to the use of a function call **Library/Function used:** * The `push()` method is a built-in JavaScript function that adds elements to an array. **Special JS feature/syntax:** None mentioned in this benchmark definition. However, it's worth noting that the spread operator (`...`) was introduced in ES6 and has become a widely accepted syntax in modern JavaScript development. **Other alternatives:** * Other methods for adding elements to an array could include: + `unshift()` method + Array literals (e.g., `[1, 2, 3]`) + Spread operator with `Array.from()` + Creating a new array using the `concat()` method
