# Uppercase const?
|
|
|
|
Examine the following code:
|
|
|
|
```js
|
|
const birthday = '18.04.1982';
|
|
|
|
const age = someCode(birthday);
|
|
```
|
|
|
|
Here we have a constant `birthday` for the date, and also the `age` constant.
|
|
|
|
The `age` is calculated from `birthday` using `someCode()`, which means a function call that we didn't explain yet (we will soon!), but the details don't matter here, the point is that `age` is calculated somehow based on the `birthday`.
|
|
|
|
Would it be right to use upper case for `birthday`? For `age`? Or even for both?
|
|
|
|
```js
|
|
const BIRTHDAY = '18.04.1982'; // make birthday uppercase?
|
|
|
|
const AGE = someCode(BIRTHDAY); // make age uppercase?
|
|
```
