In JavaScript
Write an HTML5 page with JavaScript that creates a custom object to store information about a vehicle. Create the object in an external JavaScript file. The vehicle must have at least four properties, one being direction which will have a value between 0 and 359 degrees. Add two methods called left and right which when invoked will subtract and add 10 degrees respectively to the direction property. Also add a method displayAll that will display all the properties of the custom object in an alert box. Instantiate two variables of the custom object in the <body> tag of the HTML5 page and provide buttons for the three methods defined for each instantiation.
