How to set up Tensorflow.js for machine learning in your browser

Until recently, just getting started writing your first line of machine learning code required a hefty upfront investment in time and money. Last year, I built my own PC specifically for machine learning. I researched the parts and assembled it myself. I'm still trying to wrangle the computer's configuration and libraries and make it work with various frameworks. The good news is that getting started with machine learning today has never been easier.
