Why do we need libraries?
We donât actually need libraries but they are a useful tool to have in the tool box because they can save time and effort when it comes to coding. Instead of creating a certain type of functionality from scratch it may be easier to use that same functionality which some one else has already created and put up as opensource for the world to use freely. We can also build up our own library of re-usable functions and make them available to others to use if they wish.

- To make our jobs as web developers more comprehensible and less difficult. Libraries are files that contains many functions that are useful when operating a web page. As a programmer and web developer you want to implement code that others have already written instead of wasting time writing new code.

Helps us to build on top of code. Because we are able to re-use existing code. Effectively saving tons of time.

We need libraries in order to save time trying to create code which is already functional tried and tested leaving more time for creating your own bespoke program.

- Libraries allows us to re-use existing code being this a good and more efficient programming practice. Every time we re-use code we are not wasting our time writing code that another programmer has already written.

JS library allows us to use codes that another developer has already done, so that we donât waste our time writing codes that another programmer has already written.

To have more time to geek out on blockchain by reusing code that has already been written by someone else.

There are many common problems in programming that appear often. It doesnât make sense to rewrite them from scratch every time. There is probably already a library that someone else has created, that contains solutions to many of the tasks that we are trying to solve.

Libraries are used so that we dont have to write a lot of code if someone already created what we need.

Libraries helps to diminish redundancy in code design. There is no need to re-invent the wheel.

They are helpful in save time and memory because you do not have to recreate the functionality you want, thus allowing less memory to be used for your program.

JavaScript is not consistent across browsers. You donât want to waste time creating abstractions for all the discrepancies between browsers. Letâs say you are starting three different projects at the same time, youâll probably reuse the abstractions you have written, and your projects will probably have very similar file architecture and build process. The problem is that you donât want to repeat this manual bootstrapping procedure each time you start a new project. Enter frameworks.
Frameworks help you by minimizing the effort of initialization, testing and deployment of your project, allowing you to focus on whatâs really important: your application. A good framework should be easy-to-setup, and in my opinion, flexible in a âpay for only what you eatâ fashion.
