Script Preparation code:
function formatNode(data) { return data.map(row => { const { id, label, ...properties } = row; return { id, label, properties: _.mapValues(properties, v => _.first(v)) }; }); } function format(data) { return data.map(row => formatt(row)) } function formatt({id, label, ...properties}) { return { id, label, properties: _.mapValues(properties, v => _.first(v)) } } function formatNode2(data) { return data.map(row => { const { id, label, ...properties} = row; return { id, label, properties: Object.values(properties).flat() }; }); } function format2(data) { const {id, label, ...prop} = data return { id, label, properties: Object.values(prop).flat() } }
Tests:
Function B
const input = [{ id: 1, label: 'label 1', property_1: ['prop_1'], property_2: ['prop_2'] }, { id: 2, label: 'label 2', property_3: ['prop_3'], property_4: ['prop_4'] } ] const functB_res = format(input)
Function A
const input = [{ id: 1, label: 'label 1', property_1: ['prop_1'], property_2: ['prop_2'] }, { id: 2, label: 'label 2', property_3: ['prop_3'], property_4: ['prop_4'] } ] const funcA_res = formatNode(input)
Function C
const input = [{ id: 1, label: 'label 1', property_1: ['prop_1'], property_2: ['prop_2'] }, { id: 2, label: 'label 2', property_3: ['prop_3'], property_4: ['prop_4'] } ] const functC_res = formatNode2(input)
Function D
const input = [{ id: 1, label: 'label 1', property_1: ['prop_1'], property_2: ['prop_2'] }, { id: 2, label: 'label 2', property_3: ['prop_3'], property_4: ['prop_4'] } ] const functD_res = input.map(inp => format2(inp))

Measuring the performance of JavaScript functions is crucial for optimizing code and ensuring it runs efficiently across different browsers, devices, and platforms. **Benchmarking Definition** The provided JSON represents a benchmarking definition, which outlines the test scenario and script preparation code. In this case, we have four individual test cases (Functions A, B, C, and D) that compare different approaches to format a given input data structure. **Script Preparation Code** The script preparation code defines four functions: `formatNode`, `format`, `formatt`, and `formatNode2`. These functions are used to transform the input data structure into a standardized format. The main differences between these functions lie in how they extract and process properties: 1. **`format`** and **`format2`**: Both functions use the `_` function from Lodash (a utility library) to map values over an object's properties and return a new object with only the first value of each property. 2. **`formatNode`**: This function maps over the input data structure, extracts the `id`, `label`, and properties, and then flattens the properties using the `.flat()` method. 3. **`formatNode2`**: Similar to `formatNode`, but uses the `.flat()` method to flatten properties in a single step. **Benchmark Options** The four test cases compare different approaches: 1. **Function A (format)**: Uses `_mapValues` and `.first(v)` from Lodash to extract and process properties. 2. **Function B (formatt)**: Similar to Function A, but uses `formatt` instead of `format`. 3. **Function C (formatNode2)**: Uses the `.flat()` method to flatten properties in a single step. 4. **Function D (format2)**: Uses `_mapValues` and `.first(v)` from Lodash to extract and process properties. **Pros and Cons** Here's a brief analysis of each function: 1. **Function A (format)**: * Pros: Easy to understand, uses Lodash for utility functions. * Cons: May be slower due to the use of `mapValues` and `.first(v)`. 2. **Function B (formatt)**: * Pros: Similar to Function A, but with a different naming convention. * Cons: Same limitations as Function A. 3. **Function C (formatNode2)**: * Pros: Flattens properties in a single step using `.flat()`. * Cons: Uses a different approach that may be less intuitive for some developers. 4. **Function D (format2)**: * Pros: Similar to Function A, but uses `_mapValues` and `.first(v)` from Lodash. * Cons: Same limitations as Function A. **Latest Benchmark Results** The provided JSON includes the latest benchmark results for each test case, showing the number of executions per second for each browser and device. The results indicate that: * **Function D (format2)** is the fastest, followed closely by **Function C (formatNode2)**. * **Function A (format)** and **Function B (formatt)** are slower due to their use of `mapValues` and `.first(v)`. Overall, the benchmark results suggest that Function D (format2) is the most efficient approach, but Function C (formatNode2) is a close second. The choice between these functions ultimately depends on personal preference and the specific requirements of your project.
