将JavaScript变量呈现为Liquid模板的一部分

var username = "John Doe";
var age = 25;

<p>Welcome, {{ username }}!</p>
<p>Your age is {{ age }}.</p>

// 引入Liquid.js库
const Liquid = require('liquidjs').Liquid;

// 创建Liquid实例
const engine = new Liquid();

// 定义JavaScript变量
var username = "John Doe";
var age = 25;

// 创建Liquid模板
var template = `
<p>Welcome, {{ username }}!</p>
<p>Your age is {{ age }}.</p>
`;

// 渲染Liquid模板
engine
  .parseAndRender(template, { username: username, age: age })
  .then((output) => {
    console.log(output);
  })
  .catch((error) => {
    console.log(error);
  });

<p>Welcome, John Doe!</p>
<p>Your age is 25.</p>
