VS Code autocomplete/intellisense not working

Question

Building my first React project from https://frontendmasters.com/courses/complete-react-v5/ on VS Code for Windows 10.

Have installed prettier, eslint. Using Parcel to transpile the code. The intellisense is only working on index.html file. Nothing on js files. Have looked through old answers and none of them proved to be helpful. A bit of a noob here, a step by step solution will be helpful
