Libraries - Reading Assignment

[Sergio_Garay]

1. Why do we need libraries?
   You can use libraries to save time because you can reuse code that has been written before.

[1984]

We need library so one do not have to re-invent the wheels. Someones stored in a library his findings making life of other devs much easier. Let’s use it and put our energy on something more useful

[Vinsenzo]

1.Because, there is no need to re-create the wheel…as programmers, we should re-use existing code when we can, so that we don’t waste our time writing code that another programmer has already written.

1. We need libraries so we don’t have to code everything from scratch

We need libraries so that we dont have to rewrite code that others have already created

[MoeezMalik]

1 - Libraries allow for greater efficiency when programming as it allows us to re-use pieces of code (where appropriate) that another programmer has written and made available for other programmers to use. Libraries contain functions which may be useful for whatever you are coding, and saves you a lot of time also.

Why do we need libraries?

We need libraries so that we do not have to re-write commonly used functions on our own. Instead of “re-inventing the wheel” we can use open libraries to embed the functionality we are looking for. This saves time, prevents many mistakes, and in a way gives a familiar look to many functions we see across many pages.

1. Why do we need libraries?

1. We need libraries so we are not having to constantly re-create code all the time. Once we solve for a problem and create a function we never have to re-write the same function again. It saves SOOOOOO much time and headache so developers can tackle real creative issues for their programs.

A library is a collection of re-usable routines which can be included into your application. Without these a programmer would simply re-write there own code each time. It’s a way to share code in a modular fashion and benefit from what others have created.

1. Why do we need libraries?

As programmers, we should re-use existing code when we can, so that we don’t waste our time writing code that another programmer has already written.

In JavaScript, the way we do that is by using a library . A library is a JavaScript file that contains a bunch of functions, and those functions accomplish some useful task for your webpage.

1. To save time building code but also so that we can create more functionality by building on past code.

[Mark_Dalton]

Why do we need libraries? (Much the same as what javascript learned from the opensource movement in the 1980s-present). And we use libraries in programming languages. So this concept is useful for other programming also…

1. Simplifies local code. [clean code, reliable, consistent across sites/devs, efficient, etc…]
2. Saves a lot of time for a lot of people.
3. Normally well tested and examined by many.
4. Security is often well examined.
5. Code is often improved through many people suggesting improvements.
6. Performance is commonly optimized…
7. Helps encourage creativity, innovation, sharing, and forks trying new ideas/features.
8. Often promotes healthy competition (and sometimes not so healthy competition) but ideas are explored.
9. And many more reasons…

1. Why do we need libraries?

We use libraries to build our JS project by reusing the JavaScript features and functions that others have tested and proven the codes. Like Lego building blocks, libraries help us to save project time and using special functionality and features to build a more robust application.

[Dougal]

1. Why do we need libraries?

To avoid remaking the wheel and save a ton of time.

[Toddness]

1. Why do we need libraries? So we don’t need to reinvent the wheel and create a whole lot of code that has already been written, repetitively. Especially for the visual side and set up / functionality of websites. We can then concentrate on the IP and uniqueness of our work that we wish to put forward and display.

[Bozidar]

1. Why do we need libraries?
   We use libraries to short our time waste on writting a code that is already written ready for reuse

[Daniel_Haydn]

We need libraries to save time in programming. Either by not needing to write every tool from scratch, or by making code more easy to read because other developers used the same tools.

1. Why do we need libraries?

Because there no need to reinvent the wheel. We can use the knowledge out there as building blocks for our own projects.

[Narnia]

We need libraries so we can reuse code that has already been written to save time and use it to build upon to keep innovating. Also, reusing code that has been time tested reduces the risk of bugs.
