Signs You Might Be an Exceptional Programmer Without Realizing It
Written on
Chapter 1: The Challenges of Programming
Coding is a demanding task, especially when striving to produce software that remains relevant and functional over many years. Crafting code that will be effective a decade from now is no small feat. A programmer who can achieve this while maintaining productivity truly stands out in the field.
Here are some lesser-known signs that you might be a remarkable programmer, even if you don't recognize it.
Section 1.1: Maintaining a Clean Build
Imagine your organization tasks you with developing an application that allows users to order food from local restaurants. As you write the code for the login page, you compile it and receive a warning, but no errors. Under pressure to meet a deadline, you choose to overlook that warning.
As you continue coding, more warnings accumulate—seven this time—but you ignore them all. Before long, you find yourself staring at thousands of warnings, desperately trying to locate the six that are critical to fix. The time you saved by ignoring those warnings now haunts you.
If you had addressed the warnings early on, you wouldn't be in such a predicament. Programmers who prioritize a clean build and tackle warnings proactively are exceptional. They even resolve issues like null pointer exceptions, understanding that neglecting warnings today can hinder future productivity.
Section 1.2: Avoiding Unnecessary Context
Effective programmers avoid bloating the codebase with redundant information. They strive to write concise code that omits unnecessary context. For example:
const House = {
houseSize: "small",
houseColor: "blue",
houseCity: "xyz"
};
An efficient programmer would write:
const House = {
size: "small",
color: "blue",
city: "xyz"
};
There’s no need to repeat established information if the object name already conveys it. This practice helps keep the codebase clean and manageable.
Section 1.3: Eliminating Extraneous Code
Excessive code can create unnecessary complications and slow down processes. Some programmers add extra lines merely to entertain readers, unaware that this can lead to hundreds of additional lines over time.
These lines often seem necessary, but upon closer examination, they may serve no real purpose. If you’re someone who enforces a strict no-extra-code policy, you’re on the path to becoming a highly efficient programmer.
It’s common to find dead code—segments that are no longer in use. For instance:
function oldDistanceCalculator(x1, x2) {
// do what you want
}
function newDistanceCalculator(x1, x2) {
// do what you want
}
let total = newDistanceCalculator(0, 2);
Here, oldDistanceCalculator is unnecessary. It’s best to remove such code, as version history will always allow for retrieval if needed later.
Chapter 2: Understanding Before Changing
Section 2.1: The Importance of Context
A common pitfall for programmers is rewriting code without fully understanding its context. Every programmer has unique problem-solving approaches, and what seems like a straightforward fix might overlook the original intent.
An efficient developer takes the time to comprehend existing code, the rationale behind data structures, and design decisions before making modifications. This careful consideration is vital for maintaining code integrity.
Section 2.2: Writing Focused Functions
Long functions can be frustrating and confusing for anyone who has to navigate them. Early in my career, I thought fewer functions would impress my peers, but I quickly learned that clarity is more important than brevity.
After reading "Clean Code," I adopted the principle of writing functions that focus on a single task. For example:
function enrollStudents(students) {
students.forEach(student => {
const studentRecord = database.lookup(student);
if (studentRecord.isActive()) {
enroll(student);}
});
}
This function does two things. A better approach would be to split it:
function enrollActiveStudents(students) {
students.filter(isActiveStudent).forEach(enroll);
}
function isActiveStudent(student) {
const studentRecord = database.lookup(student);
return studentRecord.isActive();
}
This separation simplifies debugging and testing, making it easier for everyone to follow.
Section 2.3: Mastering Your IDE
IDEs are invaluable tools that simplify many aspects of programming. Unlike previous generations, who faced considerable challenges without these tools, today’s programmers can enjoy streamlined coding experiences.
Yet, many fail to utilize IDE capabilities fully. To maximize productivity, familiarize yourself with keyboard shortcuts and explore the myriad features your IDE offers. If you're optimizing your IDE usage, you're undoubtedly excelling in your programming journey.
