Package description

What is @babel/plugin-proposal-optional-chaining?

The @babel/plugin-proposal-optional-chaining package is a Babel plugin that allows developers to use the optional chaining syntax in JavaScript. Optional chaining enables developers to read the value of a property located deep within a chain of connected objects without having to check that each reference in the chain is valid.

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

Optional Property Access

Safely access a property on an object. If 'obj' is null or undefined, 'value' will be undefined instead of throwing an error.

const value = obj?.prop;

Optional Method Calls

Safely call a method on an object. If 'obj' or 'obj.method' is null or undefined, 'result' will be undefined instead of throwing an error.

const result = obj?.method?.();

Optional Element Access

Safely access an array element. If 'arr' is null or undefined, 'item' will be undefined instead of throwing an error.

const item = arr?.[index];
