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

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');
