Why scripting language is required

A bug has to occur first before engineers are forced to write the tests they should have written in the first place. Just a touch of realism here why static languages are still effective when it comes to bugs. It does the heavy lifting for developer's laziness. Flexibility: you don't have to worry about the static type system. Speed of development: an interactive language allows you to write code and test it faster.

Built-in types: usually script languages provide dictionaries, lists, tuples, sets, etc. More dynamic features: you can "eval" code at runtime very easily. Maybe because you are not sure the code will work as expected, because there's no static analysis. With a statically-typed language you can write a whole program without any testing.

And static analysis won't help you there more than a spellchecker will do while writing a book. Maybe you're a genious, but most of the people in this world don't get it right the first time. Yes, the probability of bugs will always exists, but with static analysis the number of bugs decreases drastically, you don't have to test each line you write.

Also, it's much more powerful than a spellchecker, it's also a semantic checker, you cannot pass an apple to a method that expects an orange, it tells you if what you are writing doesn't make any sense.

And "passing apples instead of oranges" are the easiest problems to spot, you can also write assertions on the runtime types. So script is the easiest thing to make work in general, that's why people use it. Initial development time is one of the smallest time sinks in the development process. Maintenance and managing complexity in large systems is a much larger time sink.

Many say they write in C because its quicker to develop in, so the issue isn't solely speed of development, but design time. Because Python is like flying:. Are there already libraries or tools that assist you?

If performance is really an immediate concern, stick with the compiling languages. That is good and all but i cant imagine using a scripting language over C except when you dont have a choice like perhaps for an addon. Why not? Sure, C could eventually do the same Adrian Godong. Except when it's a dragon disguised as a duck, but that's a different matter entirely. English is ambiguous, this is why it isn't used as a programming language.

This is also why Duck typing doesn't scale. That will be more helpful to SO and everyone else who revisited this question in the future.

Today, a difference between programming and scripting languages is becoming more and more blurry since compilation can be pretty fast modern hardware and compilation techniques. Scripting or writing scripts is like programming within a program. The traditional approach with scripting is such that one would write scripts to automate certain functionality within another program.

Scripting would perform a very specific task like go through a text file to extract all digits. With Programming language, one is writing software that runs independently of a parent program. With programming language, a developer is usually involved in a project which is creating much more functionality than just a traditional script. Lines are blurred today; scripting is very powerful today and performing the task which once used to lie in programming —zone.

Scripting is a subset of programming. One should only be concerned about the language itself and how well suited it is for the required job. Every language has its strength and weaknesses.

This allows users from around the world to join in the improvement process. Other pros include:. There are not a whole lot of cons to using scripting languages. Also, installing an interpreter program can be a hassle. Finally, sometimes scripts are slower than programs.

You may find one that interests you. We suggest you find one that makes sense to you before you commit to a programming bootcamp that focuses on that language. A programming bootcamp is great in that it not only teaches you how to code but also prepares you for a career in tech. Most programming bootcamps last less than a year and they provide career services and different payment methods that allow all types of people to start a career in the tech industry.

Learning a scripting language is the easiest way to get your feet wet in the coding world. There are bountiful resources out there to help you try each one until you find one that makes sense to you. Just remember to take it slow, be patient with yourself, and aim to start with small projects, instead of a large one.
