Using setInterval in a JavaScript class

I just figured out how to use setInterval in a JavaScript class. This little snippet shows how I used setInterval in a recursive way.

function MyClass() {}
 
MyClass.prototype.doNext = function( pArray ) {
	clearInterval( this.interval );
 
	if( pArray.length > 0 ) {
		// do something with the array record
		this.doSomething( pArray.pop() );
 
		// call this function again in a couple of milliseconds
		var scope = this;
		var milliseconds = 100;
		this.interval = setInterval( function(){ scope.doNext( pArray ) }, milliseconds );
	} 
} 
 
MyClass.prototype.doSomething = function( pRecord ) {
	// do something
}
 
var myObj = new MyClass();
myObj.doNext( myArray );
