ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
@antv/util
Advanced tools
@antv/util is a utility library that provides a collection of functions for common programming tasks. It is part of the AntV ecosystem, which is a suite of data visualization tools. The library includes functions for data manipulation, type checking, deep cloning, and more.
Type Checking
The @antv/util package provides various type-checking functions to determine the type of a given value. In this example, `isString` is used to check if a value is a string.
const isString = require('@antv/util/lib/type/isString');
console.log(isString('Hello World')); // true
console.log(isString(123)); // false
Deep Clone
The `deepClone` function creates a deep copy of an object, ensuring that nested objects are also cloned. This is useful for creating independent copies of complex data structures.
const deepClone = require('@antv/util/lib/deepClone');
const obj = { a: 1, b: { c: 2 } };
const clonedObj = deepClone(obj);
console.log(clonedObj); // { a: 1, b: { c: 2 } }
console.log(clonedObj === obj); // false
Data Manipulation
The `groupBy` function allows you to group an array of objects by a specified key. This is useful for organizing data into categories or groups.
const groupBy = require('@antv/util/lib/array/groupBy');
const data = [
{ category: 'fruit', name: 'apple' },
{ category: 'fruit', name: 'banana' },
{ category: 'vegetable', name: 'carrot' }
];
const groupedData = groupBy(data, 'category');
console.log(groupedData); // { fruit: [{ category: 'fruit', name: 'apple' }, { category: 'fruit', name: 'banana' }], vegetable: [{ category: 'vegetable', name: 'carrot' }] }
Lodash is a popular utility library that provides a wide range of functions for data manipulation, type checking, and more. It is widely used and has a large community. Compared to @antv/util, Lodash offers a more extensive set of utilities and is more commonly used in the JavaScript ecosystem.
Underscore is another utility library that offers a variety of functions for common programming tasks. It is similar to Lodash but has a smaller footprint. While @antv/util is part of the AntV ecosystem, Underscore is a standalone library that focuses solely on utility functions.
Ramda is a functional programming library for JavaScript that emphasizes immutability and side-effect-free functions. It provides a different approach compared to @antv/util, focusing on functional programming paradigms. Ramda is ideal for developers who prefer a functional style of coding.
