Updated and Optimized

[SirSlender]

Fixes the loading error and the previous lag issues reported as well as further optimization:

• Grouped related functions together and organized the code for better readability.
• Changed to consistent naming conventions for functions and variables.
• Removed unnecessary checks, such as checking if this.modules is defined in load() (it's guaranteed to be defined in the constructor).
• Replaced loose equality (==) with strict equality (===) where applicable.
• Simplified and clarified some parts of the code to improve readability.
• Removed comments that did not provide additional clarity or were redundant.
• Changed "let" to "const"
• Encapsulation
