Parsing JSON strings into JavaScript objects is fundamental for working with API responses and data storage. With over 25 years of experience in software development and as the creator of CoreUI, I’ve handled JSON parsing in countless web applications and UI components. From my expertise, the most reliable approach is using JSON.parse() with proper error handling to safely convert JSON strings to objects. This method provides fast, secure parsing while preventing application crashes from malformed data.

Converting strings to numbers is essential for form data processing, mathematical calculations, API data handling, and implementing features like calculators or numeric validation in JavaScript applications. With over 25 years of experience in software development and as the creator of CoreUI, I’ve implemented string-to-number conversion extensively in components like input fields, calculators, and data processors where reliable numeric conversion ensures proper mathematical operations and data integrity. From my extensive expertise, the most robust and recommended approach is using the Number() constructor, which provides consistent conversion behavior and clear error handling. This method is explicit, handles various string formats, and produces predictable results across different scenarios.
