Node.js repl 的启动脚本

Node.js repl（交互式解释器）是一个基于JavaScript的命令行工具，用于在终端中执行JavaScript代码。它提供了一个交互式环境，让开发者能够快速测试和调试代码，而无需编写完整的脚本或应用程序。本文将介绍Node.js repl的启动脚本，并提供一些案例代码来演示其用法。

javascript
console.log("Hello, World!");
let x = 5;
let y = 10;
console.log(x + y);
function square(num) {
  return num * num;
}
console.log(square(3));

javascript
const radius = 5;
const pi = Math.PI;
function calculateArea(radius) {
  return pi * radius * radius;
}
function calculateCircumference(radius) {
  return 2 * pi * radius;
}
console.log("半径为", radius, "的圆的面积为:", calculateArea(radius));
console.log("半径为", radius, "的圆的周长为:", calculateCircumference(radius));

javascript
function generateFibonacciSequence(n) {
  let sequence = [0, 1];
  for (let i = 2; i < n; i++) {
    const nextNumber = sequence[i - 1] + sequence[i - 2];
    sequence.push(nextNumber);
  }
  return sequence;
}
const n = 10;
console.log("斐波那契数列前", n, "项为:", generateFibonacciSequence(n));

javascript
function isPrime(number) {
  if (number < 2) {
    return false;
  }
  for (let i = 2; i <= Math.sqrt(number); i++) {
    if (number % i === 0) {
      return false;
    }
  }
  return true;
}
const num = 17;
console.log(num, "是质数吗?", isPrime(num));
