Javascript ls

If you have ever worked with a command-line interface, then you must be aware of the 'ls' command. It is used to list all the files and directories present in a directory. Similarly, the 'javascript ls' command is a way to list all the variables and objects present in the javascript environment.

The 'javascript ls' command is not an actual command, but it can be achieved by using the console object in javascript. The console object provides a method called 'dir' which can be used to list all the properties and methods of an object.

Example:

    console.dir(document);

The above code will list all the properties and methods of the document object, which represents the current webpage being displayed in the browser.

We can also use the 'window' object to list all the global variables and functions present in the javascript environment.

Example:

    console.dir(window);

The above code will list all the global variables and functions present in the javascript environment.

Using the 'dir' method of the console object, we can also explore any custom objects or variables present in our javascript code.

Example:

    var myObj = {
        name: "John",
        age: 30,
        city: "New York"
    }
    console.dir(myObj);

The above code will list all the properties of the 'myObj' object.
