使用Object.assign可能解决方案。

var b = [{"cat_id":"1","cat_name":"teaching"}], a = [{"username":"r","password":"r"}],
    res2 = [Object.assign({}, ...a.concat(b))];
  
    console.log(res2);

您可以使用带扩展语法的Object.assign() 。

var b = [{"cat_id": "1","cat_name": "teaching"}];
var a = [{"username": "r","password": "r"}];

var result = [Object.assign({}, ...a, ...b)]
console.log(result)

您可以使用扩展函数来合并对象

$.extend( a, b);
