Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
he is primarily designed for use in JavaScript environments, limiting its utility in non-JavaScript projects.
The official documentation lacks comprehensive examples and explanations for complex encoding/decoding tasks, leading to confusion among users.
he does not natively handle all international character encodings, which can lead to issues when processing text with non-ASCII characters.
While he is optimized for performance, the additional encoding and decoding operations can introduce noticeable latency in high-throughput environments.
