When You Run Npm Install After 6 Months

Thinking about learning JavaScript: PANIK . Seeing the $29.217 yearly salary: KALM . Discovering that JavaScript thinks 0 > null is false, but 0 >= null is true: EXTREME PANIK . JavaScript's type coercion is like that friend who makes up rules during board games. "No, see, zero is equal to null when it's convenient, but also completely different when it's not. Why? Because I said so."

OH. MY. GOD. The absolute TRAUMA of modern frontend development captured in one image! 😱 On the left, we have the React ecosystem pointing a BAZILLION packages at us like we're being held hostage in dependency hell. React-router-dom, TypeScript, Axios, Tailwind, and twenty other packages just SCREAMING at you to install them before your project can even render "Hello World." It's like being at a buffet where you MUST eat everything or the chef gets offended! And then there's Angular on the right - just standing there... menacingly... with its all-in-one framework. One download and you're set, but at what cost to your SOUL?! This is why frontend developers have eye bags deeper than the node_modules folder. Our package.json files have more dependencies than I have emotional issues - and that's saying something! 💀

Content det ic even (num: Addition, subtraction, multiplication, and division. These are the four mathematical operations I was taught during my childhood education, and their operators, t; , are very familiar. I was not taught , the modulus operator, which I recently discovered can be quite useful and interesting in its own right. The modulus operator, written in most programming languages as or mod, performs what is known as the modulo operation. You next response, understandably, might be, "That doesn't clarify anything," so let's take a closer look: The modulus operator - or more precisely, the modulo operation - is a way to determine the remainder of a division operation. Instead of returning the result of the division, the modulo operation returns the whole number remainder. Some examples may help illustrate this, as it's not necessarily intuitive the first time you encounter it: 5 1 0 5 divided by 1 equals 5, with a remainder of 0 5 2 1 5 divided by 2 equals 2, with a remainder of 1 It may be helpful to think back to your early math lessons, before you learned fractions and decimals. Mathematics with whole numbers behaves differently - when dividing numbers that aren't even multiples, there's always some amount left over. That remainder is what the modulo operation returns. If this seems strange, boring, or not particularly useful, bear with me a bit longer - or just skip ahead to the use cases. The Modulo Operation Expressed As a Formula As one final means of explication, for those more mathematically inclined, here's a formula that describes the modulo operation: a - (n floor (an)) By substituting values, we can see how the modulo operation works in practice: 100 7 2 100, n 7 100 - (7 floor (1007)) 2 If you don't find the formula helpful, don't worry - I didn't either at first Some people find this abstract representation helps deepen or clarify their understanding of the operation, but you don't need to know it A final note here - if you're wondering how the modulo operation functions with negative numbers or decimals, that's a bit outside the scope of this article. For our purposes here, we'll only be dealing with positive integers. return num 2

When you finally switch to TypeScript for type safety but then sprinkle *any everywhere like Agent Smith clones. The irony is delicious - you've become the very thing you swore to destroy. That strict typing lasted about as long as my commitment to writing unit tests. For the uninitiated, any is TypeScript's escape hatch that basically says "trust me bro, I know what I'm doing" while completely defeating the purpose of type checking. It's the programming equivalent of putting duct tape over your check engine light.

The perfect documentation of programmer naming hell. When Twitter rebranded to "X," some poor dev somewhere had to refactor thousands of variables from sensible names like "tweet" to... "x"? And what's the verb now? "X-ing"? This is what happens when marketing decisions crash into code bases. Somewhere, a senior developer is drinking straight from the bottle while staring at search-and-replace results that broke 47 unit tests.

Oh, the absolute HORROR of 12-year-old you thinking that hbglp , vbglp , and cdc were the height of programming sophistication! Nothing screams "elite hacker" quite like variable names that look like someone smashed their keyboard while having a seizure, am I right? And that LINE 210? SWEET MOTHER OF SPAGHETTI CODE, it's longer than a CVS receipt! That single line is basically a novel written in the ancient tongue of "I-have-no-idea-what-future-me-will-think." The nested ternaries, the eval() calls, the complete and utter disregard for human readability—it's like looking at the Necronomicon of JavaScript. Young developers everywhere: this is your brain on "looking cool." Please, for the love of all that is holy, use descriptive variable names and hit that Enter key once in a while. Your future self (and literally anyone who has to touch your code) will thank you instead of plotting your demise. 💀
