javascript - 当我将对象插入数组时要添加的字符串

Question

我需要在使用 writeFileSync 生成的 js 文件中添加两个字符串

这是代码示例

const svgs = [];
var n = 2;

for (var i = 0; i < n; i++) {
  svgs.push(Cog.prototype.render());
  svgs.push(Manna.prototype.render());
}

fs.writeFileSync(`client/data/${name}.json`, JSON.stringify(svgs));

这是我生成的js文件(数组中的两个对象)

[{"xmlns":"http://www.w3.org/svg/2000","viewBox":{"viewBox":"0 0 64 64"},"width":{"size":64},"height":{"size":64},"fill":{"fill":"currentcolor"},"path":{"d":{"pathData":"M 2 2 L 62 2 L 62 62 L 2 62 L 2 2"}}},{"xmlns":"http://www.w3.org/svg/2000","viewBox":{"viewBox":"0 0 64 64"},"width":{"size":64},"height":{"size":64},"fill":{"fill":"currentcolor"},"path":{"d":{"pathData":"M 2 2 L 62 2 L 62 62 L 2 62 L 2 2"}}}]

我的问题是如何添加两个字符串，这一个在开头 const svgs = 和 export default svgs 在末尾，以使我的文件生成看起来像这样

const svgs = [{"xmlns":"http://www.w3.org/svg/2000","viewBox":{"viewBox":"0 0 64 64"},"width":{"size":64},"height":{"size":64},"fill":{"fill":"currentcolor"},"path":{"d":{"pathData":"M 2 2 L 62 2 L 62 62 L 2 62 L 2 2"}}},{"xmlns":"http://www.w3.org/svg/2000","viewBox":{"viewBox":"0 0 64 64"},"width":{"size":64},"height":{"size":64},"fill":{"fill":"currentcolor"},"path":{"d":{"pathData":"M 2 2 L 62 2 L 62 62 L 2 62 L 2 2"}}}] export default svgs;

fs.writeFileSync(client/data/${name}.json, "const svgs =" + JSON.stringify(svgs)) + "export default svgs" ;
