Hire A Programmer Who Gets Your Code 100% Right The First Time
The problem with hiring a programmer isn’t technical. It’s emotional.
As a programmer, you are always trying to improve yourself. You’re looking to learn new things, to take on new challenges and to grow in your professional life. You are always striving to be better, so it’s only natural that you expect the same from others. When you’re interviewing a candidate, you want to find someone with the same drive, who will be as dedicated as you are, not just today but in the future.
It’s hard to assess a person’s dedication from their resume or cover letter because those are just words. To see the real deal, you must look beyond those papers and start digging into their background. During the interview process, you’ll ask candidates about their past experiences: what projects they worked on and why they chose them.
If you don’t know what a linter is, it is a tool that has made programmers lives easier in many languages by pointing out patterns of bugs, inconsistencies and bad practices. Programmers always strive to write efficient and clean code and linters are helpful tools to achieve this goal.
There are three kinds of programmers:
1. Programmers who can count, and
2. Programmers who cannot count.
Now, one might argue that writing code has very little to do with being able to count. But let’s face it, if you cannot count then you are going to end up in a world of trouble sooner or later. Because counting is a fundamental operation in computer science. I mean, what kind of programmer would you be if you were not able to tell the difference between zero and one?
I’d say these two groups are easy to recognize: The ones who can count have their programs working correctly. The ones who cannot count have their programs running all the time.
There is a third group of programmers though, which is not as easy to recognize at first sight as the other two groups:
3. Programmers who write code which never fails, but also never works correctly either.
In the past, developers had to spend a lot of time and effort making sure their code worked correctly.
There were so many things to worry about: browser compatibility, usability, performance, cross-platform support…
And then there are the potential bugs that could occur because you or someone on your team forgot to check if a variable was undefined or misspelled a function name.
These types of errors can cost a development team hundreds of hours in testing, fixing and retesting.
JSHint uses a flexible configuration file where you can specify which rules to enforce or ignore (for example if you want to use a variable before it’s defined). You also have an option to configure JSHint using comments in your source files. This allows each developer on your team to have different settings without having them stored in version control.
Every programmer has lint. Lint shows up as bugs and inconsistencies in code, and it’s important to get rid of them. But if you’re not careful, you can spend a lot more time cleaning up lint than necessary.
When you first start with a new programming language, the easiest way to learn is to write code that works. Once you’ve written your first program, the hard part is over, and then it’s just a matter of writing more code and learning new features along the way.
But once you’ve been writing code for a while, your skill level starts to plateau, and so does your ability to deal with lint. At this point, it becomes important to clean up the code that’s already there before adding any new features. The only problem is, you’re not sure where to start.
The answer is simple: Start by looking at all the places where your current code is not doing what you expected it to do. These are the “bugs” in your code—that is, they’re the problems that are preventing your program from working as intended.
That seems obvious enough, but there’s actually an even better method: Rather than looking at specific lines of code, look at all the places where your current code
