Streamline Error Handling with JavaScript’s New ?= Operator

JavaScript developers, tired of messy try-catch blocks? The new ECMAScript Safe Assignment Operator (?=) is here to make error handling simpler and cleaner. Here’s what it does:

What is the ?= Operator?

  • Instead of writing multiple try-catch blocks, ?= handles errors in one line.

  • It returns two values: [error, result]. If there’s an error, the first value is the error, otherwise, it’s null and the result is returned.

const [error, result] = ?= someOperation();
if (error) {
console.error('Error occurred:', error);
} else {
console.log('success:', result);
}

Why You’ll Love It:

  • Good readability and easy to debug: Cleaner code that's simpler to follow.

  • Less nesting: No need for multiple try-catch blocks.
