Develop a JSON object with a unique format by combining elements from two separate arrays using JavaScript

Question

Develop a JSON object with a unique format by combining elements from two separate arrays using JavaScript

I've searched extensively on stack for a solution but couldn't find one, so I'm reaching out here for help:

Let's consider two arrays: one with "keys" and the other with "values"

For example:

keys = [CO2, Blood, General, AnotherKey, ... ]
values = [[2,5,4,6],[4,5,6],[1,3,34.5,43.4],[... [

The goal is to create specific Json structure like this:

[{
        name: 'CO2',
        data: [2,5,4,6]
    }, {
        name: 'Blood',
        data: [4,5,6]
    }, {
        name: 'General',
        data: [1,3,34.5,43.4]
    }, {
         ...
    }, 
}]

I attempted to manipulate strings and encode them as json, but it doesn't seem to be the right approach. I also tried using JSON.PARSE and JSON.stringify without success. If anyone knows the correct way to implement this, please share!

EDIT:

I realized that "name" and "data" are not strings but objects.

Answer №1

Below is a method to achieve the desired result:

keys = ["Dog", "Cat", "Rabbit", "Fish"]
values = [[4,9,12],[6,3,8],[7,5,10],[2] ]

const output = keys.map((key, index) => {
  return {"name": key, "data": values[index]}
})

console.log(output)

Alternatively, you may want to reconsider using an object for easier access to key/value pairs:

keys = ["Dog", "Cat", "Rabbit", "Fish"]
values = [[4,9,12],[6,3,8],[7,5,10],[2] ]

const output = {}
for (let j=0; j<keys.length; j++) {
  output[keys[j]] = values[j]
}

console.log(output)

This data structure allows for quick retrieval of information using keywords like output.Dog. On the other hand, iterating through arrays would be necessary with the current format.

(Please note that searching for JSON methods was not relevant to your question as you are dealing with data transformation rather than JSON manipulation. JSON simply represents a data object in string form.)
