let propVariableName = 'nominalName' // expression
const data = {
  a: 1,
  [propVariableName]: 2 // assign nominalName as computed property
}
// use value of expression's computed property
data.nominalName // #-> 2

let propVariableNames = [ {'nominalName1: 1'}, {'nominalName2': 2}, {'nominalName3': 3}]
 
// iterate propVariableNames
let data = { }
data[propVariableName]: propVariableName.getValue()
