【问题描述】：

我有这样的数组数据

Subcategories:["Wooden Furniture","Office Furniture","Kitchen Furniture","Modular Office Furniture","Industrial Furniture","Steel Furniture","Living Room Furniture","|Storage and Display Furniture","Entryway Furniture","Inflatable Furniture","Patio Furniture & Accessories","Storage and Display Furniture"," Office & Commercial Furniture "]

现在我想为其中的每个元素分配相同的键。基本上我想制作关键对值。 请帮忙 。谢谢

【参考方案1】：

您可以使用Array.prototype.map。

const directories = Subcategories.map(sub => 
  return  your_keyname: sub 
)
