Many library creators make both development and production versions of their libraries available. Comments and tips, as well as other non-minified code, are included in the development versions. Production versions are frequently minified and compressed for usage on live sites.
Some libraries are even accessible via content delivery networks (CDNs), including cdnjs, Google Hosted Libraries, jsDelivr, and Microsoft Ajax Content Delivery Network, to name a few.
Libraries And Their Working
Frameworks provide you with a structure to build your project around (like a skeleton). The framework supplies page templates that developers use to generate this structure, where certain places are kept aside for entering framework code. This format varies from the library format as in that the programmer decides where to use the library code.
Developers use various different frameworks and libraries for different reasons. Each has its own pros and cons. When selecting one, you should keep your objectives and goals for your website or application in mind.
