You haven't feel what's on programmer's head i see.
We have a plan, think of the code, then start coding. That's how it works.
However, Don't make an (graphic) designer the same as programmer. We do not "decorate" or "frame". We're more of getting stuff works.
If you are referring to how different a code was written on different languages, Like in Python:
```
while True:
print("Hello world")
```
In go:
```
package main
func main() {
for {
print("Hello world")
}
}
```
In js:
```
while (true) {
console.log("Hello world")
}
```
And In C:
```
#include
void main() {
while (true) {
printf("Hello world\n")
}
}
```
It's all depending on what language that the programmer use or prefer. There are language that is easier to learn (high level lang, but sometimes offer less control over computer), machine friendly (low level lang like C), and so on.
