Why is 'this' for inner function 'parse' is same as 'IntegerParser' but for 'fiterBy' function is Global object? Since 'this.parse' and 'this.filterBy' both are inner functions.

@Vishal-Lia It is because we are assigning a new object to prototype of ParseParameter. In case of objects the this refers to the object itself.

How would be in case I use the prototype syntax, I mean, instead of this.filterBy write IntegerParse.protoype.filterBy, how could I attach the context?

@JoseRojas You can in that case use JavaScript's call or apply or bind methods for specifying the context or reference of this keyword. Read more here: medium.com/@omergoldberg/…
