HELP, React not working in codepen

#1

Hello all,

Can you help me?
Why is my React App not working in codepen?

Thanks, Oxana

You have two versions of react and two versions of react-dom. I recommend working with the development versions and remove the other two.

Once you fix that, take a look at the browser console and the errors showing there and see if you can resolve them first.

You are using a component that doesn’t exist. Maybe a typo?

Uncaught ReferenceError: IoMdPower is not defined

Line 205:
<button id="power_btn" style={this.state.powerStyle} className="power_btn" onClick={this.handleClickBtn.bind(this)}> <IoMdPower /> </button>
