YAML vs JSON: Which Should You Choose?
Choosing between YAML and JSON depends on your project. YAML is ideal for human-edited configuration files, while JSON is perfect for APIs and strict data exchange. Understanding their differences helps developers pick the right format for clarity, performance, and maintainability.
📌Example Conversion
📥 Example JSON
{
"database": {
"host": "localhost",

Does YAML support comments?
Yes. YAML supports inline comments using the # symbol, while JSON does not.
Can YAML replace JSON?
Not entirely. YAML is great for configs, but JSON remains dominant for APIs and structured data exchange.
Which format is faster to parse?
JSON parsing is generally faster due to its strict and lightweight syntax.
Is YAML prone to errors?
Yes. YAML’s flexibility can lead to indentation errors if not handled carefully.
