Convert into custom object from array of nested array of numbers-CodePudding

I have an array of nested array of numbers and I am trying to convert it into array of object with x, y, z value.

I have the following data

[ 
 [1, 2, 3],
 [2, 3, 4], 
 [4, 5, 6]
]

My expected output is something like this

[ 
  { x: 1, y: 2, z: 3 }, 
  { x: 2, y: 3, z: 4 }, 
  { x: 4, y: 5, z: 6 } 
]

I have done this but I don't think its a standard solution. Any better way anyone can suggest?

data.map((point, i) => {
   return {
     x: point[0],
     y: point[1],
     z: point[2],
  }
})

CodePudding user response：

There is no better way in the sense of another (quicker) approach of doing this. map() is what you would need to to.

But you could (arguably) improve the readability/ conciseness of the code by using array destructuring and leaving out the explicit return statement. Note that I am also using enhanced object literals.

const input = [ 
 [1, 2, 3],
 [2, 3, 4], 
 [4, 5, 6]
]

const output = input.map(([x, y, z]) => ({x, y, z}));
console.log(output);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Using this approach it is very obvious what the result would be therefore I would prefer this, but your solution is fine.

CodePudding user response：

This would also work. Using array destructuring. This cleans your solution a bit more.

const data = [
  [1, 2, 3],
  [2, 3, 4],
  [4, 5, 6]
]

const output = data.map(([x, y, z]) => ({x, y, z}))

console.log(output)
