JavaScript - My Misc Notes

Scope

• Lexical scope: function written within function can access all of the parent's vars and parms.
• Function can be called before it is defined - before in the text.
• You can define a regular function anywhere in the code.
• Pronoun this is calculated when the code is executed. If we call a method that uses this outside of the object it belongs to, this will be undefined.

Modules

• IIFE way
• More common: define( [array], object); It comes from CommonJS and RequireJS more or less (see this). If object is a function, its parms are 1 to 1 with elements of the array, each of which specifies a dependency module e.g. 'rs/form/abstract/invoice.controller'. It is guaranted that the function will run only once even if more than one module list this module as their dependency.
