将 JSON object 字符串转换为带有字符串键的数组

Question

I have an JSON string with an object: {"foo1":"bar1","foo2":"bar2"}

How can I convert this into an array with string keys? The result should be the same as this:

var myArray = [];
myArray["foo1"] = "bar1";
myArray["foo2"] = "bar2";

I need a very fast way, since I have to convert often arrays with more than 100,000 items.

To literally create your "array with extra properties" , you can use Object.assign()

 const json = `{"foo1":"bar1","foo2":"bar2"}`; // assign the parsed object properties on to an array const myArray = Object.assign([], JSON.parse(json)); console.log("myArray:", myArray); // still an empty array // but the properties do actually exist console.log("myArray.foo1:", myArray.foo1); console.log("myArray.foo2:", myArray.foo2);
