The best developers write the worst first versions of code.

When we think of the best developers, we often imagine meticulous coding and perfectly architected systems following best standards and practices. However, the reality is quite different. The best developers don’t strive for perfection in their first attempt — instead, they intentionally create imperfect, functional first versions and improve it later on.

Do you know what is senior developer ?

A senior developer writes code like a junior / middle — focusing first on getting the logic right. But what makes them senior is what happens next: they go back, improve the code, and optimize it until it’s clean, efficient, and ready for production.

Here’s an example to illustrate the concept: Who wrote this code?

function calculateTotalPrice(prices: number[], tax: number): number {
    let total = 0;
    for (let i = 0; i < prices.length; i++) {
        total += prices[i];
    }
    return total + total * tax;
}

const prices = [10, 20, 30];

console.log(calculateTotalPric…
