50+ Coding Challenges and Why Everyone Should Learn them.
Coding is a valuable skill that can open up many doors in your career. If you're just starting out, it can be helpful to work through some beginner coding challenges. These challenges will help you learn the basics of coding and give you a foundation to build on.
Sometimes Coding can be fun and rewarding. Coding can be a fun and challenging hobby. It's a great way to exercise your brain and learn new things.
Specially when you starting out and first you have understand the basic syntax of the Programming Language. And as the time pass you learn and Adopt anf Implement.
Why Programming Not FrameWork First
I believe if you learn how to program and implement solutions and build problem solving skills you can do much in your life. and by focusing on programming, you gain a deep understanding of the core concepts, logic, and problem-solving skills that are applicable in any programming context. This versatility allows you to adapt to new frameworks or technologies as they emerge, ensuring that your skills remain relevant and valuable in the long term.
Why I choose Golang
For like many other programming language Golang have something unique like in Golang you have to write some code to implement a solution but as for other programming language there are build in methods or Operators, For Example:
Dart
String reverseString(String str) {
return str.split("").reversed.join();
}
TypeScript
function reverseString(str: string): string {
return str.split("").reverse().join("");
}
RUST
fn reverse_string(str: &str) -> String {
let reversed: String = str.chars().rev().collect();
reversed
}
Golang
func reverseAString(str string) string {
var chars []rune = []rune(str)
for i, j := 0, len(chars)-1; i < j; i, j = i+1, j-1 {
chars[i], chars[j] = chars[j], chars[i]
}
var reversed string = string(chars)
fmt.Println("Reversed:", reversed)
return reversed
}
Most of other language have a lot of build in functionality but for Golang sometimes you have to write you own functionality to make things work. I am not saying you can not the same with other language Of course you can but when you implement something by yourself you learn a lot.
