Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
The tool is primarily designed for JavaScript, limiting its utility in non-JavaScript environments.
Given that it's an open-source project with a narrow focus, the community might be small, leading to slower issue resolution and feature development.
The tool needs to process each character carefully to handle astral symbols and ansi escape codes, which could introduce a slight performance penalty for very long strings.
