ComponentDidMount is not being called - very simple app

Question

I used create-react-app to create this very simple app. ComponentDidMount is never invoked.

import React, { Component } from "react";

class App extends Component {
  ComponentDidMount() {
    console.log("MOUNTED");
  }

  render() {
    return (
      <div className="App">
        <h1>Hi Lol</h1>
      </div>
    );
  }
}

export default App;

Method names are case sensitive, so you should start with a lowercase: componentDidMount instead of ComponentDidMount.

Cool, I'd appreciate if you could mark it as the right answer. – Gleb Kostyunin Dec 05 '18 at 22:56
This is most likely the cause. I assume the component is being imported into a HOC with reactDOM as well. – Jacob Dec 05 '18 at 22:56
