如何在json中传递变量来获取数据

{
  "name": "{{name}}",
  "age": {{age}},
  "address": "{{address}}"
}

const template = {
  "name": "{{name}}",
  "age": {{age}},
  "address": "{{address}}"
};

const data = {
  "name": "John",
  "age": 30,
  "address": "123 Main St"
};

const result = Mustache.render(JSON.stringify(template), data);
console.log(result);

{
  "name": "$name",
  "age": $age,
  "address": "$address"
}

const json = `{
  "name": "$name",
  "age": $age,
  "address": "$address"
}`;

const data = {
  "name": "John",
  "age": 30,
  "address": "123 Main St"
};

const result = json
  .replace("$name", data.name)
  .replace("$age", data.age)
  .replace("$address", data.address);

console.log(result);
