New programming languages are born every day. Dart, Go, Kotlin, Elixir and more! Beating the learning curve can be difficult, but there are some tips that will help you to get through.
There are some steps you want to take to accelerate the learning process and increase your fluency in the programming language or framework you are learning.
Master the language. Then learn frameworks.
Some people tend to learn frameworks, like Ruby on Rails, without getting to know the language, in this case, Ruby. That's a huge problem, especially when talking about Rails, that plays with Ruby as a DSL (domain-specific language).
Solve coding challenges.
There are a lot of websites like LeetCode, HackerRank and Project Euler that can help you to reach fluency. You'll learn more about the syntax, libraries, and logic. That's a great way to prepare yourself for an interview too.
Use StackOverflow and Code Review as much as you want.
When you start solving coding challenges, you'll find problems. To solve them, you can use StackOverflow, a website that needs no introduction.
The ace in the hole is on Code Review, a StackExchange community, the same network from StackOverflow. The whole point about Code Review is to get a review of your code from experts in the language you are learning. Take a look at the beginner's section and join this awesome community!
GitHub is essential to beat the learning curve. There you'll find production code in the language you are learning. If you are confident to contribute, that's even better.
Install a linting tool.
Linters are code-analyzer tools that flag bugs, idiomatic offenses, stylistic errors and more. A linting tool will flag the error for you to fix, and that's when you learn. For Ruby, I use RuboCop as a linter.
When I was learning Python, I transferred my C# knowledge to Python. Thatā??s a great way to learn a new programming language, but itā??s not enough to reach fluency, because you canā??t learn the idiomatic way of programming in that language.
To illustrate, take a look at this Python code (credits to Oleksandr Kaleniuk):
def matrix_of_floats(matrix_of_anything): n = len(matrix_of_anything) n_i = len(matrix_of_anything) new_matrix_of_floats =  for i in xrange(0, n): row =  for j in xrange(0, n_i): row.append(float(matrix_of_anything[i][j])) new_matrix_of_floats.append(row) return new_matrix_of_floats
versus the Pythonic way (idiomatic Python):
def matrix_of_floats(matrix_of_anything): return [[float(a_ij) for a_ijin a_i] for a_iin matrix_of_anything]
To learn how to code idiomatically, you have to read a lot of code written by the pros.
This one is cool. The main purpose of learning a programming language is to build something with it. When I was learning Ruby, I used Rails framework to build a blog, a todo app, a Wikipedia clone and a Rotten Tomatoes like the website.
Building something will evolve every aspect of your learning.
Don't give up.
Beating learning curves can be really hard. You need time and focus to get there. Don't give up because you may be closer than you think. If you are stuck, ask for help. There's a lot of resources out there.
