Add customization to entity form

Create a js file with a vendor prefixed function which accepts a single parameter called executionContext:

function abc_my_customization(executionContext) {
  const formContext = executionContext.getFormContext();
  formContext.data.entity.attributes.forEach(function(attribute) {
    const attributeName = attribute._attributeName;
    const label = formContext.getControl(attributeName ).getLabel()
    const value = attribute.getValue();
    console.log(label + ": " + value);
  });
}

See docs for more info on using the Client API object model (i.e. execution context, form context, grid context, etc…)
