Libraries - Reading Assignment


#141

Why do we need libraries?
So we don’t have to write code from scratch, when other people have already done so. By using libraries we can save time and money, and increase performance and security – because libraries have probably been tested widely and debugged. When linking to an outside library, it’s important to make sure that it’s coming from a legitimate source. Otherwise, we’re opening the door of our website or application to malicious actors.


#142

Libraries enable programmers to re use existing CODES without having to programme new ones them- Its like recycling existing codes functions


#143
  1. Why do we need libraries? - Libraries allow the programmer to leverage code that has already been written so that time is not wasted re-inventing the wheel.

#144

Why do we need libraries? : To allow us to import and reuse existing software components


#145

we need libraries in order to save our time by using someone others code to solve a particular problem


#146

We use libraries so we don’t waste time re-writing code that has already been written for us.


#147

Why do we need libraries?
We need them to avoid reinventing the wheel of coding by reusing js functionality.


#148

To re-use code that has already been written and proved to adequate for the task you wish to program.

Saves time and effort.


#149

Libraries in simple terms is ‘prerendered’ code, code that has already been created and (possibly) tested, so we ourselves don’t need to create things from scratch, since most of the time the librarie we are putting into our code will not be our focus.

  1. Why do we need libraries?

Briefly, we need and use libraries to re-use all ready written code so we can use the time to write new ones!
I quote what many all ready said: “we don’t need to re-invent the wheel all the time”. Excellent explanation.


#151

Why do we need libraries?

We can read and reuse other existing code without really inventing the wheel all over again. Saves time and it is nice to share your code and knowledge so people can also work on it.

Shared and open source information makes the code more efficient and more accessible to the public which can improve the industry to work better :wink:

The short answer is to save time.

The long answer is that using a Library is using the concept first attributed to the 12th Centry French philosopher Berard of Chartres.

“And this is not at all because of the acuteness of our sight or the stature of our body, but because we are carried aloft and elevated by the magnitude of the giants.”

The phrase was later popularised in English by Isaac Newton.


#153

Why do we need libraries? To re-use code that somebody else had written to save us time.


#154
  1. Why do we need libraries?

A library is a JavaScript file that contains a bunch of functions, and those functions accomplish some useful task for your webpage. We need libraries so we can re-use the useful functions that someone else has created and can help us accomplish our tasks faster and easily. They also help us not re-invent the wheel every time we have new problem.
Some famous libraries are below.

  1. jQuery (oldest and most famous library)
  2. React (by facebook)
  3. Angular
  4. Ember
  5. Vue
  6. Backbone

#155
  1. Why do we need libraries?
    To save time by using code that has already been written to provide functions we require. Rather than re-inventing the wheel and all the problems of working through the glitches of your new code. We can simply use the code from a library and reference the source.

#156

We need librariese because someone has already invented the thing we need so why do we need to go back and try to reinvent it from scratch. Libraries allow use find what we need and copy that for our usage


#157

We need them in order not to reinvent the wheel every time we want to build something


#158

To reuse code, so that we don’t waste our time writing code that another programmer has already written.


#159

to reuse other peoples code


#160
  1. We use libraries to use code for specific tasks, rather than code from nothing and waste time, it also provides a archive for developers to keep record of hard work or more efficient code.
