Speed Up Ruby on Rails Concepts
What are the advantages of Ruby over Python?
Initially we tried python but it didn't feel appropriate for me. Then we tried ruby and fell suitable.
Why we prefer ruby as good as Python
· Everything has returns a value (including 'if' statements also). Because of that, it is easier to write functional code than python and much easier to sequence commands.
· Consistent object orientation. Python go through design decisions made; that makes it hard to use object orientation. Array, size vs. Len(array) yes, you can use array. Len_ but that's just bad looking.
· Open classes. It is easy to open a class and add a method to it. But you must be careful with it, but it is the right way to solve problems (less code, more clarity).
· Anonymous blocks. Python has anonymous closures (i.e. lambda), but it must fit on a single line. In ruby, every method completely supports passing in an anonymous block. It allows you to write code and also users to make modifications to the code using variables. That can extremely powerful and easier to use in ruby. Python has a variety to deal with (decorators, generators, context managers) & to deal with the problem i.e solved 95% of the time with ruby's anonymous blocks.
Now Ruby on Rails declining does it have good carrier for junior developer who want to work as Ruby on Rails developer?
1) Initially, we consider belief that Rails is long term declining, for this question let's consider that it is true.
2) Declining does not mean it’s all over. Ruby is still in the top. It’s still a top programming language.
3) Now the thing to consider is C is up there as a top language. But there are a lot of C programmers out there and they have been programming C for decades. So if there are more C jobs there will be more C programmers with more experience trying to get them.
4)On the other side; even if there are less Ruby on Rails jobs then there are also less Ruby/Rails programmers. So the framework is young they will also have less experience as well.
5)So from a job point of view there may be fewer people applying for job in a less popular framework then in a more popular one.
6) And a rails programmer I have definitely had more problems finding rails programmers then getting rails jobs. After all, I have a lot of years of general programming experience and a decent network which both help.
7) Also, as a final touch, if you want to get good the language is going to matter less and less. A really good programmer knows various languages and frameworks and knows enough to pick up a new one very quickly. Even if rails isn't what you are programming with 20 years from now if you like it now it will give you more programming experience you will be using in 20 years.
