...make fast go now

  • compiling components and their HTML templates during a build process 

 

  • convertING to executable JavaScript code before the browser renders them

  • Early error detection : detects binding errors during build, before users see

  • Better security : compiled before served to clients, no client-side html || js evaluation, fewer injection attacks

ANGULAR

  • code splitting...only load code required to render the view they requested

  • universal rendering...server-side rendering

  • Tree-shaking...shakes out unused code
