### Description

I was developing jsleak during most of my free time for my own need.It is easy-to-use command-line tool designed to uncover secrets and links in JavaScript files or source code. The jsleak was inspired by [Linkfinder](https://github.com/GerbenJavado/LinkFinder) and regexes are collected from multiple sources.  

### Features:

- Discover secrets in JS files such as API keys, tokens, and passwords.
- Identify links in the source code.
- Complete Url Function
- Concurrent processing for scanning of multiple Urls
- Check status code if the url is alive or not
