How to create an object in an array?

Question

Node.js

for(ot of otds){
          menuOtd.push(ot.name);
          
          if(ot.pndOtd.sub == "true"){
            
          };
        };

I create in a loop - a regular array, but under a certain condition an object should be created, how to do this?
Conditionally, if the variable is equal to true, then not an element of the array "NAME" is created, but an object in which the value of NAME will be and let's say "Description"
