how to connect 2 scripts using C# / JS

how to connect script together just like a script in health bar and another in health by itself? using C#/JS

It is possible to use both languages, but you need to place them in specific folders within your project, then the way they compile means that they only work one way i.e. C# gets compiled before JS, JS can see C# but C# cannot see JS. Read this link, especially Point 3 :
