Package description

What is @babel/plugin-proposal-optional-catch-binding?

The @babel/plugin-proposal-optional-catch-binding package allows developers to use the optional catch binding syntax proposed for JavaScript. This syntax lets you use try/catch blocks without needing to specify a catch binding if you don't need it for the catch block.

What are @babel/plugin-proposal-optional-catch-binding's main functionalities?

Optional Catch Binding

This feature allows you to omit the catch binding (the error variable) when you don't need to use it within the catch block. It simplifies the syntax when the error object is unnecessary.

try {
  // some code that might throw
} catch {
  // handle the error without using the error object
}
