If you haven’t worked with JavaScript in the last few years, these three points should give you enough knowledge to feel comfortable reading the React documentation:

• We define variables with let and const statements. For the purposes of the React documentation, you can consider them equivalent to var.
• We use the class keyword to define JavaScript classes. There are two things worth remembering about them. Firstly, unlike with objects, you don't need to put commas between class method definitions. Secondly, unlike many other languages with classes, in JavaScript the value of this in a method [depends on how it is called](https://developer.mozilla.org/en-US/docs/Web/Jav

### Creating repositories with submodules
#### Adding a submodule to a Git repository and tracking a branch

If you add a submodule, you can specify which branch should be tracked via the -b parameter of the submodule add command. The git submodule init command creates the local configuration file for the submodules, if this configuration does not exist.

# add submodule and define the master branch as the one you want to track
```
git submodule add -b master [URL to Git repo] 
git submodule init 
```

RecyclerView item onClick

RecyclerView does not have an OnItemClickListener like it's predecessor, ListView. However, detecting item clicks is pretty simple.

private class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>  {

    public static class ViewHolder extends RecyclerView.ViewHolder
