When you expand the
window object, and scroll down, within it, you eventually see the variable
a: 'Hello World' and
not created inside other functions are attached to the global object.
So what that means is that, in the console; if you type
'a' you get
andm when you type
window.a you also get
a and the function
n we created are not inside a function, they are lexically sitting inside the global object.
When your code is executed, an
execution context is created by the JavaScrip engine which also created a global object for example, the window object if you are in a browser. variable
this, is created, and
this will serve as the link to the outside environment.
The execution context is running your code!
