Key characteristics affecting these criteria include readability, writability, reliability, and efficiency. Readability pertains to how easily code can be understood, while writability assesses how easily code can be written. Reliability focuses on the language's ability to produce correct results consistently, and efficiency relates to the performance and resource utilization of programs written in the language.
