What is @babel/plugin-syntax-throw-expressions?

@babel/plugin-syntax-throw-expressions is a Babel plugin that allows you to use the `throw` expressions syntax in your JavaScript code. This syntax enables you to throw exceptions directly within expressions, making it easier to handle errors in a more concise and expressive manner.

What are @babel/plugin-syntax-throw-expressions's main functionalities?

Throw Expressions in Conditional (Ternary) Operator

This feature allows you to use the `throw` statement directly within a ternary operator. If the condition is false, an error is thrown.

const value = condition ? 'valid' : throw new Error('Invalid condition');

Throw Expressions in Logical Operators

This feature allows you to use the `throw` statement within logical operators like `||`. If `someValue` is falsy, an error is thrown.

const value = someValue || throw new Error('someValue is required');
