angular is like spring,
typescript is like java
Why is it that js gave birth to this content, instead of java supporting the conversion to js, and then directly using frameworks such as java"s spring?

  angular ,  typescript  is essentially  JS , you can use  JS  syntax.  JAVA  syntax writing  JS  is not impossible, but unnecessary. 
  angular ,  typescript  syntax is biased towards  JAVA  syntax because the  JAVA  specification is really suitable for engineering. 
 language limitations, JS language advantage is weakly typed language, flexible, but also high barriers to use, and no large-scale engineering experience. 
 java is a strongly typed language with relatively low barriers to use, perfect biosphere and high support from various major manufacturers. The key is that there are a series of perfect resources, such as engineering / IDE, etc.
