Just a simple filter.

({"userDetail":[
 {
   "Name": "Scottic Mangry",
   "Age" : "12", 
 },
 {
   "Name": "Joneson Mangly",
   "Age" : "18", 
 },
 {
   "Name": "Saoyu Wang",
   "Age" : "15", 
 },
]}).userDetail.filter(e=>e.Name.includes("Mang"))

Something like:

let data = {
    "userDetail":[
     {
       "Name": "Scottic Mangry",
       "Age" : "12", 
     },
     {
       "Name": "Joneson Mangly",
       "Age" : "18", 
     },
     {
       "Name": "Saoyu Wang",
       "Age" : "15", 
     },
    ]
}

let needle = "Mang";
let result = data['userDetail'].filter(el => el.Name.includes(needle));
console.log(result);

needle is the string we are searching for inside the Name property of the data.userDetail object

includes is case sensitive, so if you want to match results regardless of case it's easiest to lowercase everything first

As cmgchess say in comments Using filter and includes would do the job for you: to make it more declarative and readable I put it inside a function called findName

const objs = {
  "userDetail": [{
      "Name": "Scottic Mangry",
      "Age": "12",
    },
    {
      "Name": "Joneson Mangly",
      "Age": "18",
    },
    {
      "Name": "Saoyu Wang",
      "Age": "15",
    },
  ]
}

function findName(name) {
  return objs.userDetail.filter(user => user.Name.includes(name))
}
let searchObj = "Mang";
console.log(findName(searchObj));

you can do it using Array.filter, Array.values and includes

const data = {"userDetail":[
 {
   "Name": "Scottic Mangry",
   "Age" : "12", 
 },
 {
   "Name": "Joneson Mangly",
   "Age" : "18", 
 },
 {
   "Name": "Saoyu Wang",
   "Age" : "15", 
 },
]}


const search = (data, search) => data.filter(d => Object.values(d).some(v => v.includes(search)))

console.log(search(data.userDetail, "Mang"))
