JS 请解释下这两个参数啥意思function highlight(string

Question

function highlight(strings, ...values) {

    let str = '';

    strings.forEach((string, i) => {

      str += `${string} <span contenteditable class="hl">${values[i] || ''}</span>`;

    });

    return str;

  }

  const name = 'Snickers';

  const age = 100;

  const sentence = highlight`My dog's name is ${name} and he is ${age} years old`;

  document.body.innerHTML = sentence;

  console.log(sentence);

  

  请解释下highlight这个函数的两个参数，最好能详细点es6语法
