Script Preparation code:
var hasZero = []; var withoutZero = []; for (var i = 0; i < 1000; i++) { hasZero.push(Math.floor(Math.random() * 100)); withoutZero.push(Math.floor(Math.random() * 100) + 1) }
Tests:
Array.some
var tempResult = Math.round(Math.random()) ? hasZero.some(v => v === 0) : withoutZero.some(v => v === 0);
Array.filter
var tempResult = Math.round(Math.random()) ? hasZero.filter(v => v === 0) : withoutZero.filter(v => v === 0);
Array.indexOf
var tempResult = Math.round(Math.random()) ? hasZero.indexOf(0) > -1 : withoutZero.indexOf(0) > -1;
Array.includes
var tempResult = Math.round(Math.random()) ? hasZero.some(v => v === 0) : withoutZero.includes(v => v === 0);
Array.find
var tempResult = Math.round(Math.random()) ? hasZero.some(v => v === 0) : withoutZero.find(v => v === 0);

, generated one year ago):
To explain what is tested on the provided JSON, I'll break it down into sections. **Benchmark Definition** The benchmark definition represents a JavaScript function that is to be executed in different ways. In this case, there are four functions: 1. `Array.some()`: Returns `true` if at least one element in the array satisfies the condition. 2. `Array.filter()`: Returns an array containing only the elements of the original array that satisfy the condition. 3. `Array.indexOf()`: Returns the index of the first occurrence of the specified value in the array, or `-1` if it's not found. 4. `Array.includes()` and `Array.find()`: These functions are used to test alternative implementations for `Array.indexOf()`. **Options Compared** The benchmark compares different options: * `Array.some()` vs `Array.filter()` vs `Array.indexOf()` vs `Array.includes()` vs `Array.find()` * These options are compared in terms of execution speed and performance **Pros and Cons** * **`Array.some()`**: Pros: Simple, efficient, and widely supported. Cons: May be slower than other methods for large arrays or when a specific index is needed. * **`Array.filter()`**: Pros: Can return an array with multiple elements that satisfy the condition, making it useful for filtering. Cons: May be slower than `some()` due to creating an additional array. * **`Array.indexOf()`**: Pros: Fast and efficient for finding a single element in an array. Cons: Returns an index, which may not be what the developer expects (e.g., if the index is `-1`, it means the value was not found). * **`Array.includes()`**: Pros: Similar to `indexOf()`, but returns a boolean value instead of an index. Cons: May be slower than `indexOf()` due to its overhead. * **`Array.find()`**: Pros: Returns the first element that satisfies the condition, making it useful for finding a single result. Cons: May be slower than `some()` or `indexOf()`, especially if the array is large. **Library and Special JS Features** There are no libraries used in this benchmark definition. However, there is an example of using `Math.random()` to generate random values within the scripts. **Other Considerations** * The benchmark uses a small array size (1000 elements) for simplicity. * The condition `v === 0` or `v === 1` is used for testing, which is a simple and symmetric test case. * The benchmark does not account for edge cases like empty arrays or null/undefined values. **Alternatives** If you wanted to create similar benchmarks, you could consider using: * Other JavaScript engines (e.g., Node.js, Chrome DevTools) * Different array sizes or data distributions * Additional methods or functions (e.g., `Array.includes()` with a different condition) * More complex scenarios (e.g., nested arrays, objects)
