Package description
@babel/plugin-proposal-throw-expressions is a Babel plugin that allows you to use throw expressions in your JavaScript code. This proposal introduces the ability to throw exceptions directly within expressions, making it easier to handle errors in a more concise and expressive manner.
Throw expressions in conditional (ternary) operators
This feature allows you to throw an error directly within a ternary operator, making it easier to handle invalid conditions without needing additional if-else statements.
const value = condition ? 'valid' : throw new Error('Invalid condition');Throw expressions in logical operators
This feature allows you to throw an error directly within logical operators like || and &&, providing a more concise way to enforce required values or conditions.
const value = someValue || throw new Error('someValue is required');This package provides the syntax support for throw expressions but does not transform the code. It is useful if you want to use throw expressions in your code but handle the transformation separately.
This package transforms throw expressions into equivalent code that can be executed in environments that do not support the syntax natively. It is similar to @babel/plugin-proposal-throw-expressions but focuses on transforming the code for compatibility.
