| 3 In my professional experience as a full-stack engineer, I primarily work with languages like Python, JavaScript, and Ruby, which don’t provide strict control over memory management. Contract work requiring languages like C or C++ is rare, as most clients prefer "modern" languages that prioritize ease of use over low-level control. Even on the few occasions when I did write C or C++ code, my focus was not on performance optimization. However, I recently observed some C++ code that changed my perspective. | 8 In my professional experience as a full-stack engineer, I primarily work with languages like Python, JavaScript, and Ruby, which don’t provide strict control over memory management.
