javascript - When does it become too many libraries? -

i have been asked create small javascript application, takes in data (invoices) , returns outcomes (eg whether paid?)

to me creation have used multiple libraries , frameworks, have used;

• backbone js
• jquery
• bootstrap

i looking @ other plugins use? point ever come have used much? if so, when happen?

many thanks, luke

when have multiple libraries being used, come across case code being run simultaneously, causing massive slow down. if there slow down of performance, it's programmer move of processing server. if have multiple levels of encapsulation of code, can have multiple libraries being used simultaneously.

even if have many libraries, problem may cause bandwidth used during transfer.

please remember, can move of business logic server. can make code:

• readable
• scalable
• structure
• secure

but, these come programming.
