JS编程实现简单模板引擎变量替换

    render (str) {
      return function (obj) {
        str = str.replace('year', obj.year)
        str = str.replace('(month)', obj.month)
        str = str.replace('$(day)', obj.day)
        return str
      }
    },
    tranform () {
      const year = '2018'
      const month = '9'
      const day = '21'
      const str = this.render('year-(month)-$(day)')({ year, month, day })
      console.log(str)
    }
