Loop through object get value using regex key matches Javascript

Question

var obj = {
 Fname1: \"John\",
 Lname1: \"Smith\",
 Age1: \"23\",
 Fname2: \"Jerry\",
 Lname2: \"Smith\",
 Age2: \"24\"
}

with an object like this.

Answer 1

You can sidestep the entire problem by using a more complete object instead:

var objarr =  [
            {fname: "John",  lname: "Smith", age: "23"},
            {fname: "jerry", lname: "smith", age: "24"}
          ] ;

objarr[0].fname; // = "John"
objarr[1].age;   // = "24"

Or, if you really need an object:

var obj =  { people: [
            {fname: "John",  lname: "Smith", age: "23"},
            {fname: "jerry", lname: "smith", age: "24"}
          ]} ;

obj.people[0].fname; // = "John"
obj.people[1].age;   // = "24"

Now, instead of using a regex, you can easily loop through the array by varying the array index:

for (var i=0; i
