Why is this map for loop code not working?-CodePudding

Someone with experience should be able to understand the error with ease, but for me it is hard, I tried learning online about map and for loop but no luck understanding the error, can someone please help me.

let jsonVal = [["ID","Name","Age"],["212","David","38"],["213","Mike","42"]]

let newJsonVal = [] 
 for (let i =1; i< jsonVal.length-1; i  ) {
    let newObject ={}
     jsonVal[i].map((d,j) => { 
       newObject[jsonVal[0][j] = d]
      })
    newJsonVal.push(newObject);
     console.log(newJsonVal);
 }

The output should look something like this:

[
  {
    "ID": "212",
    "Name": "David",
    "Age": "38"
  },
  {
    "ID": "213",
    "Name": "Mike",
    "Age": "42"
  }
]

Thanks for your help in advance

As the previous answer but this time with multiple objects:

let jsonVal = [["ID","Name","Age"],["212","David","38"],["213","Mike","42"]]
let [keys, ...objs] = jsonVal;
let newJsonVal = []
objs.map((obj, i)=>{
    const newObj = keys.map((key, i)=>[key, obj[i]]);
    newJsonVal.push(Object.fromEntries(newObj));
})
console.log(newJsonVal)
