The article analyses Markdown's minimalist design, its ambiguous syntax, security flaws such as ReDoS and XSS vulnerabilities, and the growing gap between its original simple transliteration goal and the complex compiler‑like features developers now demand.
A detailed benchmark shows Go’s regexp engine is about 25 times slower than Python for a matching input, but in worst‑case scenarios Go remains microseconds while Python can take seconds, thanks to Go’s linear‑time Thompson NFA design versus Python’s exponential backtracking engine.
This article explains how maliciously crafted regular expressions can cause catastrophic backtracking, leading to Regular Expression Denial of Service (ReDoS) attacks, illustrates the problem with code examples, and provides practical mitigation strategies for developers.
