Package description
The 'code-point-at' npm package provides functionality to retrieve a Unicode code point from a string at a given position. This is particularly useful for handling Unicode characters that are represented by two JavaScript characters (surrogate pairs).
Get code point at specific position
This feature allows you to retrieve the Unicode code point of a character at a specified position in a string. It is especially useful for strings containing characters that may be represented by surrogate pairs in JavaScript.
const codePointAt = require('code-point-at');
let str = '𠮷野家';
let codePoint = codePointAt(str, 0);
console.log(codePoint); // 134071This package is a polyfill for the String.prototype.codePointAt() method defined in ECMAScript 2015 (ES6). It offers similar functionality to 'code-point-at' by allowing retrieval of the code point of a character at a given position in a string. The main difference is that 'string.prototype.codepointat' extends the String prototype, making it available as a method on any string instance, whereas 'code-point-at' is used by requiring the module and calling it as a function.
Punycode.js is a robust Punycode converter that fully complies with RFC 3492 and RFC 5891, and works in nearly all JavaScript environments. This package includes functionality to handle Unicode code points, which can be seen as similar in handling specific Unicode operations like 'code-point-at'. However, Punycode.js is more focused on encoding and decoding between Unicode and ASCII characters, particularly for internationalized domain names (IDNs), making it broader in scope compared to the specific functionality of 'code-point-at'.
