最简单的方法就是 string.replaceAll()了吧

const stringReplace = (template: string, obj: { [k: string]: string }) => {
    const keys = Object.keys(obj)
    keys.forEach(k => {
        template = template.replaceAll(`{{${k}}}`, obj[k])
    })
    return template
}

也可以考虑用template来做

const stringReplace2 = (template: string, obj: { [k: string]: string }) => {
    return eval('`' +  template.replaceAll("{{", "${obj['").replaceAll("}}", "']}") + '`')
}

需要考虑的一点就是parameter会不会有一些奇怪的格式和符号, 最基本的应该没问题。
性能上好像是template literal会快一点。
