```typescript
import React, { useState } from 'react';

interface NeuralNetworkProps {
  inputs: number[];
  weights: number[];
  bias: number;
}

const NeuralNetwork: React.FC<NeuralNetworkProps> = ({ inputs, weights, bias }) => {
  const [output, setOutput] = useState(0);

  const calculateOutput = (): number => {
    let sum = 0;
    for (let i = 0; i < inputs.length; i++) {
      sum += inputs[i] * weights[i];
    }
    sum += bias;
    return Math.max(0, sum);
  };

  const handleClick = () => {
    const result = calculateOutput();

  return (
    <div>
      <button onClick={handleClick}>Calculate Output</button>
      <p>Output: {output}</p>
