Package description
The @babel/plugin-transform-optional-catch-binding package is a Babel plugin that allows developers to use optional catch bindings in their JavaScript code. This feature is part of the ECMAScript 2019 (ES10) specification and enables developers to use try/catch blocks without the need to specify a catch binding if the error object is not used in the catch block.
Optional Catch Binding Transformation
This feature transforms optional catch bindings to be compatible with environments that do not support this ES2019 syntax. It removes the need for an unused error binding in catch blocks.
try {
// some code that might throw
} catch {
// handle the error without using the error object
}This package transforms ES2015 block scoping (let and const) to ES5. It is similar in the sense that it also transforms newer JavaScript syntax to be compatible with older environments, but it focuses on variable declarations rather than catch bindings.
This package transforms ES2015 default, rest, and destructured parameters to ES5. Like @babel/plugin-transform-optional-catch-binding, it deals with transforming modern JavaScript features to ensure compatibility with older JavaScript engines, but it focuses on function parameters instead of error handling.
This package allows the transformation of the optional chaining syntax (?.) which is a feature proposed for JavaScript. It is similar to @babel/plugin-transform-optional-catch-binding in that it deals with optional syntax features, but it focuses on property access rather than error handling.
