Transform optional chaining operators to workaround https://crbug.com/v8/11558
@babel/plugin-bugfix-v8-spread-parameters-in-optional-chaining is a Babel plugin designed to address a specific bug in V8 (the JavaScript engine used in Chrome and Node.js) related to the use of spread parameters within optional chaining expressions. This plugin ensures that code using these features behaves correctly across different environments.
Fixing V8 Bug with Spread Parameters in Optional Chaining
This feature ensures that when using spread parameters within optional chaining, the code executes correctly. Without this plugin, certain versions of V8 might not handle this scenario properly, leading to unexpected behavior.
const obj = { foo: { bar: (...args) => args } };
const result = obj?.foo?.bar(1, 2, 3);
console.log(result); // [1, 2, 3]This Babel plugin allows you to use the optional chaining operator in your code. While it doesn't specifically address the V8 bug with spread parameters, it enables the use of optional chaining syntax, which is a prerequisite for the functionality provided by @babel/plugin-bugfix-v8-spread-parameters-in-optional-chaining.
This Babel plugin enables the use of the nullish coalescing operator (??) in your code. Although it doesn't directly address the V8 bug with spread parameters, it often complements the use of optional chaining by providing a way to handle default values when dealing with null or undefined.
