createElement to use block-scoped variables in for...in loops

[wo-o29]

Summary

This PR fix the createElement function to use block-scoped variables (const) in for...in loops instead of declaring the variable (let propName) at the function scope. This change aligns with modern JavaScript best practices, improving code readability and safety.

Changes

1. Replaced the function-scoped variable declaration (let propName) with block-scoped declarations (const) directly inside the for...in loops.
2. Ensured that all loops remain functionally identical to the previous implementation.

Benefits

• Improves code readability by limiting the scope of loop variables to their respective loops.
• Aligns with modern ES6+ standards and best practices for variable scoping.
• Reduces potential for unintended side effects caused by reusing a single variable across multiple loops.

Additional Notes

This change is purely a refactor and does not alter any functionality of the createElement API.
