Question

I have a input array of objects

[
  { col1: 'col1value1', col2: 'col2value1', col3: col1value3},
  { col1: 'col1value2', col2: 'col2value2', col3: col1value2}
]

Now I want to convert this into a object two arrays like below

columns:["col1" , "col2","col3"],
data: ["col1value1","col2value1" , "col1value3"] ,
      ["col1value2","col2value2" , "col1value2"]

is there any good way or faster way. as I am trying to use 2 foreach loop on all the values and creating columns and data array

Answer 1

Use Object.keys() method to get all the columns and use Array.prototype.map method to traverse the array and get the values using Object.values() method.

 const input = [ { col1: 'col1value1', col2: 'col2value1', col3: 'col1value3' }, { col1: 'col1value2', col2: 'col2value2', col3: 'col1value2' }, ]; const columns = Object.keys(input[0]); const data = input.map((x) => Object.values(x)); console.log(columns); console.log(data);
