Recently, I attempted to implement a regular expression in TypeScript:
I ran the following code: const pass = /^[\pL\pM\pN_-]+$/u.test(control.value) || !control.value;
To my surprise, an error occurred:
"Category shorthand not allowed in this regular expression dialect in Typescript"
Can someone shed some light on why this error is popping up and suggest possible solutions to resolve it?
The regex shorthand \pL is not permitted in this context.
You must utilize the full versions \p{L} instead of the shorthand:
const password = /^[\p{L}\p{M}\p{N}_-]+$/u.test(control.value) || !control.value;
