I have this example functions. How do I get the value of somVariableB as output in Main() ? I get only the undefined inside the console back.

export function childA(dbData) {

  var someVariableB = dbData.VariableB;

   return {
     <svg>
      <div>someVariableB</div>
     </svg>

import childA from ...

export function someFunctionB(dbData){
  return {
    <svg>
      <div> {childA(dbData)}</div>
    </svg>
}

import someFunctionB from ...
import someJsonDbData from ....

export function Main() {
 return (
       
        <div>
          { childB(someFunctionB(someJsonDbData).get("someIndex)}
        </div> )
    }
