Converting a JS object to an array using jQuery

Question

My application creates a JavaScript object, like the following:

myObj= {1:[Array-Data], 2:[Array-Data]}

But I need this object as an array.

Answer 1

If you want to keep the name of the object's properties as values. Example:

var fields = {
    Name: { type: 'string', maxLength: 50 },
    Age: { type: 'number', minValue: 0 }
}

Use Object.keys(), Array.map() and Object.assign():

var columns = Object.keys( fields ).map( p => Object.assign( fields[p], {field:p} ) )

Result:

[ { field: 'Name', type: 'string', maxLength: 50 }, 
  { field: 'Age', type: 'number', minValue: 0 } ]

Explanation:

Object.keys() enumerates all the properties of the source ; .map() applies the => function to each property and returns an Array ; Object.assign() merges name and value for each property.
