推荐答案
您可以使用 Array.prototype.map（）
You can use Array.prototype.map()
map（）方法创建一个新数组调用调用数组中每个元素的提供函数的结果。
The
map()method creates a new array with the results of calling a provided function on every element in the calling array.
JSON.parse（）方法解析JSON字符串，构建字符串描述的JavaScript值或对象。
The
JSON.parse()method parses a JSON string, constructing the JavaScript value or object described by the string.
var arr=[ '{"email":"abc@gmail.com","name":"Abc"}',
'{"email":"def@hotmail.com","name":"Dr.Def"}',
'{"email":"xyz@gmail.com","name":"Xyz"}',
'{"email":"cad@hotmail.com","name":"Cat"}'];
var res = arr.map(info => JSON.parse(info));
// Or simply
// var res = arr.map(JSON.parse);
console.log(res);
