How are we going to parse this type of object in angular or javascript?

How are we going to parse this type of object in angular or javascript? using for earch loop ? or parsing?. I wanted to get title value and assign it to title cause as you can see the value of title is object {‘title’: ‘Hey’, ‘instruction’: ‘Take a sad song a…75, ‘sub_title’: ‘Jude’, ‘timelimit’: ’01:05:01′} instead of “Hey” as you can see on the example. Same also with the second object. Is there a way we can do thaat?

json array of objects format

[  
   {  
      id:0,
      title:"{'title': 'Hey', 'instruction': 'Take a sad song a…75, 'sub_title': 'Jude', 'timelimit': '01:05:01'}"
   },
   {  
      id:1,
      title:"{'title': 'Assessment', 'instruction': 'Jude', 'cr…71, 'sub_title': 'Test', 'timelimit': '06:25:08'}"
   }
]

desired output

[  
   {  
      id:0,
      title:"Hey"
   },
   {  
      id:1,
      title:"Assessment"
   }
]
