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.
@babel/helper-call-delegate
Advanced tools
@babel/helper-call-delegate is a Babel helper module that assists in transforming and managing function calls, particularly in the context of handling super calls in derived classes. It is used internally by Babel to ensure that the correct context and arguments are passed when dealing with inheritance and method overriding.
Handling Super Calls
This feature allows you to handle super calls in derived classes by ensuring that the correct context and arguments are passed to the super function. The `callDelegate` function is used to invoke the super function with the specified context and arguments.
const { callDelegate } = require('@babel/helper-call-delegate');
function superCallExample() {
const superFn = () => console.log('super function');
const context = { value: 42 };
const args = [1, 2, 3];
callDelegate(superFn, context, args);
}
superCallExample();
@babel/plugin-transform-classes is a Babel plugin that transforms ES6 class syntax into a backwards-compatible ES5 syntax. It includes functionality for handling super calls and method inheritance, similar to @babel/helper-call-delegate, but as part of a broader transformation of class syntax.
core-js is a modular standard library for JavaScript that includes polyfills for various ECMAScript features, including class inheritance and super calls. While it provides a broader range of polyfills and utilities, it can be used in conjunction with Babel to ensure compatibility with older environments.
babel-plugin-transform-es2015-classes is an older Babel plugin that transforms ES2015 class syntax to ES5. It handles super calls and method inheritance, similar to @babel/helper-call-delegate, but is specific to the ES2015 version of JavaScript.
