Building JavaScript Objects and Constructors

Recreate a Similar Object

I am attempting to recreate an object similar to the one shown in the image using Chrome Dev Tools.

Console.log(TabPanel) displays information about the object, but I'm confused by how the function name is displayed as

TabPanel : f TabPanel()

with the f symbol.

I have tried using constructors and prototypes to recreate this type of object, but I haven't been successful. I am unsure how they achieved this unique display.

Answer №1

When you examine the contents in devtools, it is indicating that the TabPanel property on the logged object is a reference to a function named TabPanel, not an instance created by TabPanel, but the actual function itself. Here's a clear example to illustrate this concept:

function Example() {
}
var o = {
  ex: Example
};
console.log(o);

Please refer to the developer console for more details.

When you define a function with a specific name, it will be displayed as such in your console.

const TabPanel = function TabPanel() {};
console.log(TabPanel);

The output in the console will match what is shown in your screenshot.

If you prefer to have this function as part of an object, you can achieve that like this:

const TabPanel = {
    TabPanel: function TabPanel() { ... }
}

In this case, the function will be logged as part of an object, which can be expanded to show your named function.
