This is the basic structure of the landing page from my new React app, created according to the standard documentation:

import React, { Component } from 'react'; import logo from './logo.svg'; import './App.css'; class App extends Component { render() { return ( <div className="App"> <header className="App-header"> <img src={logo} className="App-logo" alt="logo" /> <h1 className="App-title">Welcome to React</h1> </header> <p className="App-intro"> To get started, edit <code>src/App.js</code> and save to reload. </p> </div> ); } } export default App;

My idea is to embed the logic of a Python script that I wrote- kind of simplistic "proof of concept"- into this React app, such that it can execute in the browser of the person viewing the page.

I've never built a React app before though- how can I include that python routine as part of the React app- presumably rewritten in JavaScript- so that it can execute inside of the browser?

Here is the crux of the Python function:

# This method determines whether or not the number is a Palindrome def isPalindrome(x): x = '{:.2f}'.format(x).replace('.','') a, z = 0, len(x) - 1 while a < z: if x[a] != x[z]: return False a += 1 z -= 1 return True

I've seen before that JavaScript can just have functions that are defined- for instance- at the bottom of the index page- and that they're just called by some procedural code to execute- pass them some variables- and so on- is that the right way? Maybe I should encapsulate it somehow?
