Problem: You feel your job depends on you delivering a solution written in a specific programming language and of the same standard of quality as your teammates. Alternatively, obtaining a job in the first place depends on your proficiency in a specific programming language.
Solution: The text suggests picking a language and becoming fluent in it, as it will be the main language you will be using for the next few years to solve problems. It’s a difficult choice to make, especially when looking for jobs that may been looking for specific skills and languages. It’s “important to carefully weigh the options, as it is the foundation upon which your early career will be built.” One good way to gain experience and become fluent in a language is to actually have a real problem to solve, and to “seek out opportunities to create feedback.” Becoming fluent in a language allows you to start working more on test-driven development, allowing you to check your assumptions and aiding development of new languages.
This pattern has good advice, and it’s not the first time I’ve heard someone suggest working on one language and perfecting it instead of trying to learn multiple languages at the same time and expect to be fluent in each one. An interesting tip from the text was building a toy application in the language you’re trying to pursue a job with, one that your prospective employer would be able to access. Good learning experiences come from solving real problems, school gives you a good foundation to build upon and learn from the problems you solve in your professional career. Working in the field and running into real problems, the ability to work with other people and learn from them is a big part of gaining skill. I think Java would be a practical choice to become fluent in as it’s a high demand language that receives a lot of bad press but it running on 3 billion devices. The book also mentioned the community behind these languages and all the resources you have at your disposal. They suggest taking advantage of the support network you have and attending local meetings related to that language.
