Your CSP blocks eval. So I wrote a parser.
I needed a graphing calculator that plots sin(2x) + x^2 while you type. The obvious implementation is one line: const y = eval ( expression . replace ( / x / g , String ( x ) ) ) ; It is also the one line that cannot ship, because the page sends this header: Content - Security - Policy : script - src 'self' ; object - src 'none' ; No…

- Parser has four stages: tokenization, RPN conversion, evaluation
- Goal was functional graphing calculator for dynamic expression input
