Basically a complex version of this example, done over and over, for larger methods.

  togglePanel = (newTogglePanelComponentState: Boolean) => {
    return this.setState({ panelToggleState: newTogglePanelComponentState });
  }

  togglePanel = bool => this.setState({ panelToggle: bool })

I don't understand what you're trying to demonstrate with your example. Your TS(?) example is needlessly complicated, and syntactically invalid.

Here's a better TS implementation:

  togglePanel = (panelToggle: bool) => this.setState({ panelToggle })

I agree, it wasn't a good example. More was (attempting) to make a point when inside a complex file, what I've seen. With long interface names mixed in with long variable names, contributing to larger files sizes than necessary. It varies depending on project/company. It's lowercase `boolean`.

You're right, sorry! I write TS every day at work but for some reason I sometimes forget which languages use bool and which use boolean ;)
