Hey there, fellow developer! Confused about whether to pick Node.js or Deno for your next project? Let’s cut through the noise and get straight to what matters. I’ve worked with both platforms, and I’ll share some real-world insights that’ll help you make an informed choice.

The Story Behind Both Platforms

Picture this: It’s 2009, and JavaScript is stuck in browsers. Then comes Node.js, breaking these chains and letting JavaScript run anywhere. Fast forward to 2020, and the same creator, Ryan Dahl, launches Deno, saying, “I’ve learned from my mistakes. Here’s a better way.”

        const result = await processComplexData();
        res.json(result);
    } catch (error) {
        res.status(500).json({ error: error.message });
    }
});
const processComplexData = async () => {

    return { status: 'success', data: 'processed' };
