reactjs if/else 在 object.keys 中

Question

In react, I am trying to have if/else statement inside object.keys . Is it possible? Following code gives compilation errors. Thanks

    Object.keys(processItem).forEach(key =>
        if(processItem[key] !== 0) {
            !Boolean(processItem[key])   ? delete processItem[key] : '';                    
        }
    );

Yes - you just need to wrap it in {}

  Object.keys(processItem).forEach(key =>
   { if(processItem[key] !== 0) {
        !Boolean(processItem[key])   ? delete processItem[key] : '';                    
    }}
);
