javascript - 如何使用 ES6 脚本的模板文字

Question

我一直在尝试解决关于hackerrank 的模板文字问题。它在我的本地 IDE 上运行良好，但在 Hackerrank IDE 上出现错误。这是代码二加两个数字并使用模板文字打印结果。

const sum = () => {
  let a=1;
  let b=2;
  console.log(`The sum of ${a} and ${b} is ${a + b}`);
}
module.exports = {sum}

但它正在产生以下错误。

npm WARN template-literals@1.0.0 No repository field.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.9 (node_modules/fsevents):

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

The sum of 1 and 2 is 3

我想补充一下我的看法。

const sum = (a,b) => {
  return `The sum of ${a} and ${b} is ${a + b}`;
};
module.exports = {sum}

分号在这些类型的代码中很重要
