How to change NODE and NPM version

 kodali@kodaliPC:~/SivaDocs/React/Examples/hello-react3$ node --version

v14.7.0

kodali@kodaliPC:~/SivaDocs/React/Examples/hello-react3$ npm -v

6.14.7

kodali@kodaliPC:~/SivaDocs/React/Examples/hello-react3$ nvm use 10.14.2

Now using node v10.14.2 (npm v6.4.1)

kodali@kodaliPC:~/SivaDocs/React/Examples/hello-react3$ npm -v

6.4.1

kodali@kodaliPC:~/SivaDocs/React/Examples/hello-react3$ node -v

v10.14.2

NOTE: If you close terminal, and open new terminal then if you run npm -v and node -v you will get default versions. Remember it. Again in that new terminal if you want to downgrade you have to use the command nvm use VERSION_NUMBER
