This syntax would create a new instance of a "row" class, but there is no class by that name in this video.

There is also no "row" (singular) property, and the "rows" (plural) property only contains a plain number.

this.row=new row(6) will create an instance of the object row which we don't have.

I am new with javascript. So bear with me. This may have a new instance as if you are declaring a new variable. The new keyword is usually used to create a new object, variable.

used MDN to refer back to the new keyword
