Libraries are useful functions packaged together for others to use. As someone created these functionalities we donā€™t need to write them again but we can reference them in our code to build upon them. It saves time and effort.

Libraries

    To use code that already exist. Don't reinvent the wheel!
    Keep in mind that libraries and frameworks make you download more code than necessary and slows down your program.
#28

Why do we need libraries?

We need libraries to reuse code that it is helpful to our project, this allows us to decrease the time of development

#29

We need javascript libraries to reuse the code which has been already programmed by other developers, it saves our time. :stuck_out_tongue_winking_eye:

#30

Why do we need libraries?

Libraries are useful because it helps us use functionality developed and tested by others adding it to our code saving time and effort and producing attractive useful results.

#31 
Why do we need libraries?

Libraries allow us as programmers to re-use already made code to achieve a desired outcome. A library can be imported and functions from the library can be called within our program. This ultimately saves us time.

#32

Libraries allow us to re-use existing code ā€“ for many common tasks it makes sense to not reinvent the wheel but instead use already provided (in the best case also well-tested and well-documented) libraries from other developers.

#33

Why do we need libraries?
-A library is used so we donā€™t have to reinvent the wheel. No point in spending hours writing something if it is already done and freely available.

#34

Why do we need libraries?
To reuse existing code.
To collaborate.
To write functions once and use them across several scripts/projects.
To get feedback from the comunity and improve the code.

#35

Why do we need libraries?
With the libraries , we can focus on our project without losing time in writing the code that it has been already written , we can reuse the code from libraries and we don t have to code again something that it s been coded already.

#36

Libraries help us make our code easier to read. They also enable us to use pre-written code instead of writing everything ourselves.

I have a question?:eyes:

We use the $( ) in jQuery library, but my question is =>
What happen with the syntax in the other libraries, each library has his own syntax? Please explain me because I confused

#38

We need libraries to reuse a code instead of writing it again and againā€¦and thus saving our time.

Why do we need libraries?
To re-use existing code when we can, so that we donā€™t waste our time writing code that another programmer has already written.
