Assumptions
 A) You have Maven 3.6.3 installed      (the frontend-maven-plugin requires Maven 3.6.0 or greater)
    [see learnMaven / howToInstallMaven_3.6.3.OnCentOS.txt]

 B) You have NVM installed
    [see learnNode / howToInstallNodeVersionManager.txt]

 C) You have Java 17 JDK installed
    [see learnJava / howToInstallJava_OpenJdk_OnCentos8.txt]


Procedures
  1. Install or upgrade Node and the Angular CLI
     a. Use NVM to install Node v18.17.0            # Angular 16.2 requires node 18.10.0 or later
        unix> nvm install 18.17.0
        unix> nvm alias default 18.17.0             # Set the default version in your shell to this version
    
    
     b. Verify that Node is v18.17.0 / npm is 9.6.7
        1) Open a new terminal
    
        2) Verify that node is 18.17.0
           unix> node -v
           v18.17.0
    
        3) Verify that NPM is 9.6.7
           unix> npm -v
           9.6.7
    
    
     c. Install the Angular CLI 16.2
        1) List npm global packages
           unix> npm list -g --depth 0

            └── [email protected]
    
        2) Uninstall the previous version of your Angular CLI
           unix> npm uninstall @angular/cli        # uninstall the local angular CLI
           unix> npm uninstall -g @angular/cli     # uninstall the global angular CLI
    
        3) Install Angular CLI 16.2.2
           unix> npm install -g @angular/[email protected]
    
        4) Verify the versions are good
           unix> ng version
