Script Preparation code:
var lol = { getById: () => [] }
Tests:
simple function
var artifacts = { getById: () => [] } const flatten = (artifacts, artifactId) => { const foo = (artifactId) =>{ return lol.getById(artifactId); } return [ ...foo(artifactId) ] } for(var i = 0; i < 100; i++) { flatten(artifacts, i) }
higher order function
var artifacts = { getById: () => [] } const createFlattenr = (artifacts) => { const getDependencies = (artifactId) => lol.getById(artifactId); return (artifactId) => { return [ ...getDependencies(artifactId) ] } } const flatten = createFlattenr(artifacts) for(var i = 0; i < 100; i++) { flatten(i) }

Autogenerated LLM Summary

, generated one year ago):
Measuring performance is crucial in software development, and MeasureThat.net provides a great platform for testing JavaScript benchmarks. **Overview of the Benchmark** The provided benchmark tests two approaches to creating a simple function that flattens an array of IDs: one using a higher-order function (HOF) and another using a traditional function. The HOF approach creates a function `flatten` by composing another function `getDependencies` with the `lol.getById` function, which is defined in the "Script Preparation Code". The traditional approach uses a simple function directly. **Options Compared** The benchmark compares two options: 1. **Higher-Order Function (HOF)**: This approach creates a new function `flatten` by combining another function `getDependencies` with `lol.getById`. This allows for more flexibility and reuse of the `lol getById` function. 2. **Traditional Function**: This approach uses a simple function directly, without any higher-order functions. **Pros and Cons** * **HOF Approach** + Pros: - Allows for more flexibility and reuse of the `lol.getById` function. - Can be more efficient if the `lol.getById` function is expensive to call. + Cons: - May introduce additional overhead due to the creation of a new function object. * **Traditional Function** + Pros: - Simple and straightforward, with no additional overhead. + Cons: - May not be as flexible or reusable as the HOF approach. **Library and Purpose** The `lol` object is likely a placeholder for a library that provides a utility function `getById`. In this case, it's used to retrieve an array of IDs by their index. The actual implementation of `lol.getById` is not shown in the benchmark code. **Special JS Feature or Syntax** There are no special JavaScript features or syntaxes mentioned in the benchmark code. However, it's worth noting that MeasureThat.net may use some optimizations or assumptions about the JavaScript environment to improve performance, such as using V8-specific features or assuming a specific browser version. **Other Alternatives** If you want to experiment with different approaches or libraries, here are some alternatives: * Use a different library for `lol.getById`, such as an object with method names instead of property access. * Implement the `flatten` function using a different data structure, like a Map or Set. * Experiment with different higher-order functions, such as currying or partial application. Keep in mind that the performance differences between these alternatives may be small and influenced by various factors, including the JavaScript environment, browser version, and hardware.
