A few days ago, I read an article by the author of Core-js. To be honest, it was my first time hearing about Core-js. As someone who has written some front-end code and has been keeping up with open source projects, I feel a bit ashamed.
However, there are many open source projects that are widely used but not well-known. In this article, I will take a closer look at a few of these unsung heroes of the open source world. I do not want to give them a business model or financial advice in this article. This largely depends on the author’s personal experience and values. I just want to raise more awareness about these open source projects.
