Bank’s Response to Southwest’s 56.1, ¶ 7.) In distinguishing Southwest and NetBank’s relationships with Community, NetBank asserts: “Southwest extended a line of credit to Community in exchange for a secured interest in the notes associated with the mortgage loans Community originated. NetBank purchased loans from Community without extending any line of credit to Community.” (NetBank’s Response to Southwest’s 56.1, ¶ 12.) As discussed infra, this issue need not be resolved for purposes of these motions.

⁴ Both intervenor-plaintiffs agree that Community engaged in fraud by “double-booking” loans. (Southwest’s 56.1, ¶ 13; NetBank’s Am. Intervenor Compl., ¶¶ 47-53 (Stagg Aff., Ex. 16).) Therefore, for purposes of deciding this motion, the Court shall assume that Community, in fact, did engage in a fraudulent double-booking scheme.

e builds an object named deep_thought, sets its the_answer property to 42, and creates an ask_question method. When deep_thought.ask_question() is executed, JavaScript establishes an execution context for the function call, setting this to the object referenced by whatever came before the last ”.”, in this case: deep_thought. The method can then look in the mirror via this to examine its own properties, returning the value stored in this.the_answer: 42. Constructor

Likewise, when defining a function to be used as a constructor with the new keyword, this can be used to refer to the object being created. Let’s rewrite the example above to reflect that scenario:

Instead of explicitly creating the deep_thought object, we’ll write a function to create BigComputer objects, and instantiate deep_thought as an instance variable via the new keyword. When new BigComputer() is executed, a completely new object is created transparently in the background. BigComputer is called, and its this keyword is set to reference that new object. The function can set properties and methods on this, which is transparently returned at the end of BigComputer’s execution.

most when building complex programs. I can’t count the number of times I’ve lost track of what the this keyword refers to after passing control around from function to function, and I’ve often found myself contorting my code in all sorts of confusing ways, trying to retain some semblance of sanity in my understanding of which variables were accessible where.

In typical object-

oriented programming, we need a way of identifying and referring to the object that we’re currently working with. this serves the purpose admirably, providing our objects the ability to examine themselves, and point at their own properties.

This article will tackle the problem head-on, outlining definitions of context and scope, examining two JavaScript methods that allow us to manipulate context, and concluding with a deep dive into an effective solution to ninety percent of the problems I’ve run into.

Where Am I? And Who Are You?

Every bit of your JavaScript program is executed in one execution context or another. You can think of these contexts as your code’s neighborhood, giving each line an understanding of where it comes from, and who its friends and neighbors are. As it turns out, this is important information, as JavaScript societies have fairly strict rules about who can associate with whom; execution contexts are better thought of as gated communities than as open subdivisions.

We can refer to these social boundaries generally as scope, and they’re important enough to be codified in each neighborhood’s charter, which we’ll refer to as the context’s scope chain. Code within a particular neighborhood can only access variables listed on its scope chain, and prefers interaction with locals to associations outside its neighborhood.
