Re-implementing native JavaScript methods like JSON.stringify is a high-frequency interview topic that tests your understanding of Recursion, Type Checking, and Data Structures.

Expected Behavior:

💎 Primitives: Correctly handle string, number, boolean, and null.
📦 Arrays: Convert to [...] notation, maintaining order and recursively stringifying elements.
🏺 Objects: Convert to {"key":value} notation, recursively stringifying values.
📏 Rules: Strings must be enclosed in double quotes. Objects and arrays should not have trailing commas.

Constraints:

You only need to handle JSON-serializable values (no undefined, symbol, or functions).
Ignore the replacer and space parameters found in the native API.

💡 Examples

jsonStringify({ name: "Alice", age: 25 }); 
// Output: '{"name":"Alice","age":25}'

jsonStringify([1, "test", true]); 
// Output: '[1,"test",true]'

jsonStringify("hello"); 
// Output: '"hello"'
