javascript how to normlize array into the proper format json

Question

I have an array which looks like this

var arr =  [ [{a:1}],
             [{b:1}],
             [{c:1}], 
             [{d:1}],
             [{e:1}] ]

what i want to do is to create a proper format out of it like this

 [{a:1},{b:1},{c:1},{d:1},{e:1}]

tried many sources and not able to find the best solution

Can anyone help?

Answer 1

This should work for you (Not ideal but it works)

var arr =  [ [{a:1}],
             [{b:1}],
             [{c:1}], 
             [{d:1}],
             [{e:1}] ];
//this is not ideal but it works for u
for (var i = 0; i <arr.length - 1; i++) {
  arr[i] = arr[i][0];
}
console.log(arr);

Answer 2

simply

const res = arr.flat()

or:

 const arr = [ [{ a:1 }], [{b: 1}], [{c:1}], [{d:1}], [{e:1}] ] const res = arr.map(([o])=> ({...o})) // for a copy of objects console.log( JSON.stringify( res ))

or: (without makking a new array)

 const arr = [ [{ a:1 }], [{b: 1}], [{c:1}], [{d:1}], [{e:1}] ] arr.forEach(([o],i,a)=>a[i]=o) console.log( JSON.stringify( arr ))
