function updateRecords(object,id, prop, value) {
if(value=""){
  delete object.[prop];
  console.log(object[id]);
}
else{
if(prop!="tracks"){
 object[id][prop]=value;

this is not checking the value, = is the assignment operator, you need to use the comparison
operator ===

this is wrong syntax, you can’t use dot and bracket notation at the same time

you may want to check the rest for other errors of the same kind

object.prop cannot find the property of the array. You need to access to id first. So the code becomes: object[id][prop].
