Preparing code for production

- [Instruction] Another very useful plug that we can use…is the UglifyJS webpack plug in.…What this is going to do is it's going to minify all of our code…and it's going to generate a bundle…that should be in one line.…Now the first thing I want to do here is…go to my IndexJS file and we're going to just delete everything…and replace it with a simple function.…So I'm going to say const add = (x, y)…and then this should return x + y.…

There we go.…So this is our only thing we have going on here…but we're still going to want to minify it,…in a minute.…Now the next thing I want to do is install this package…so we'll say uglifyjs-webpack-plugin-save-dev.…And once that is installed…we will be able to make use of that.…While that process is in the background lets go ahead and…make some adjustments to our webpack config file.…So several things are going to change here.…

The first thing that'll change is UglifyJSPlugin…is going to be imported rather than html-webpack-plugin.…The next thing we want to change here is our entry point.…
