GitHub Removes Malicious Pull Requests Targeting Open Source Repositories
GitHub removed 27 malicious pull requests attempting to inject harmful code across multiple open source repositories, in another round of low-effort attacks.
@visx/point
Advanced tools
@visx/point is a utility library for working with 2D points in JavaScript. It provides a simple Point class that can be used to represent and manipulate points in a 2D space, making it useful for various graphical and data visualization tasks.
Creating a Point
This feature allows you to create a new Point object with specified x and y coordinates.
const { Point } = require('@visx/point');
const point = new Point(10, 20);
console.log(point); // Point { x: 10, y: 20 }
Manipulating Points
This feature allows you to perform arithmetic operations on points, such as adding two points together.
const { Point } = require('@visx/point');
const point1 = new Point(10, 20);
const point2 = new Point(5, 5);
const sum = point1.add(point2);
console.log(sum); // Point { x: 15, y: 25 }
Distance Between Points
This feature allows you to calculate the Euclidean distance between two points.
const { Point } = require('@visx/point');
const point1 = new Point(10, 20);
const point2 = new Point(13, 24);
const distance = point1.distance(point2);
console.log(distance); // 5
point-geometry is a lightweight library for 2D point geometry operations. It provides similar functionalities to @visx/point, such as creating points, adding points, and calculating distances. However, it is more focused on performance and minimalism.
geometry-2d is a comprehensive library for 2D geometry operations, including points, lines, and polygons. It offers more advanced geometric operations compared to @visx/point, making it suitable for more complex geometric computations.
A simple class to represent an x, y
coordinate.
npm install --save @visx/point
import { Point } from '@visx/point';
const point = new Point({ x: 2, y: 3 });
const { x, y } = point.value(); // Get the coords as an object
const [x, y] = point.toArray(); // or array
point.value()
Returns an { x, y }
object with the x and y coordinates.
point.toArray()
Returns the coordinates as an array [x, y]
.
