I have a React app and I have a dictionary of symbols stored in another file in the form of securities.{asset}.symbol. For example, for Apple stock the address is stored at securities.Apple.symbol which normally evaluates to 'AAPL'.

So,

    let bb = `securities.${asset}.symbol`;

bb is now a string 'securities.Apple.symbol' How do I evaluate the string above instead of returning a string?

I have tried

 let re = Function('return ' + bb)();
 console.log('res', re));

However that console.log doesnt return anything... (whereas if

  let bb=`1+1` 

it would work and evaluate as 2)

Do you have a solution? Thanks
