What is @types/d3-array?
The @types/d3-array package provides TypeScript type definitions for d3-array, a module in the D3.js library that offers powerful data manipulation capabilities such as computing statistics, searching, sorting, and reshaping arrays. These type definitions enable TypeScript developers to use d3-array with type safety, ensuring that their code is more robust and less prone to runtime errors.
What are @types/d3-array's main functionalities?
Statistics
Compute basic statistics such as maximum and mean values of numeric arrays.
import { max, mean } from 'd3-array';
const numbers = [1, 2, 3, 4, 5];
const maximumValue = max(numbers);
const meanValue = mean(numbers);
Searching
Search for a value in a sorted array using binary search, returning the index of the value.
import { bisectLeft } from 'd3-array';
const numbers = [1, 2, 3, 4, 5];
const index = bisectLeft(numbers, 3);
Transformations
Transform arrays by merging multiple arrays into one.
import { merge } from 'd3-array';
const arrays = [[1, 2], [3, 4], [5]];
const mergedArray = merge(arrays);
Other packages similar to @types/d3-array
lodash
Lodash is a comprehensive utility library that provides a wide range of functions for manipulating arrays, objects, and other data types. While it offers similar functionalities for array manipulation, it does not specialize in data visualization or statistical operations as d3-array does.
underscore
Underscore is another utility library that offers functions similar to lodash, including array manipulation. It is less modular than lodash and d3-array, and while it provides basic operations, it lacks the specialized statistical and data manipulation capabilities of d3-array.
