C's string header file in TypeScript

• strcat
• strchr
• strcmp
• strlen
• strstr

We have 20 C functions so far - help us add more

Got a rainy Sunday afternoon and a taste for a porting puzzle?

• Get inspiration from the C math.h documentation, the C math.h source.
• Click "New file" in the appropriate folder on GitHub. This will fork the project to your account, directly add the file to it, and send a Pull Request to us.

We will then review it. If it's useful to the project and in line with our contributing guidelines your work will become part of Locutus and you'll be automatically credited in the authors section accordingly.

Character-class span helpers are useful for string scanning.

• strcspn
• strspn

Prefix-bounded string comparison still has a clean plain-value contract.

• strncmp

Character-class search maps naturally to string scanning.

• strpbrk

Last-occurrence search maps naturally to string lookup.

• strrchr
