La valeur de la variable `PATH` est une longue chaîne composée de répertoires séparés par deux-points `:` sous Linux et macOS, et par point-virgule `;` sous Windows.

Par exemple, la variable d'environnement `PATH` peut ressembler à ceci :

//// tab | Linux, macOS

```plaintext

// It splits the slice s around each instance of one or more consecutive white space
// characters, as defined by [unicode.IsSpace], returning a slice of subslices of s or an
// empty slice if s contains only white space. Every element of the returned slice is
// non-empty. Unlike [Split], leading and trailing runs of white space characters
// are discarded.
func Fields(s []byte) [][]byte {
	// First count the fields.

SSE est un standard pour diffuser des données du serveur au client via HTTP.

Chaque événement est un petit bloc de texte avec des « champs » comme `data`, `event`, `id` et `retry`, séparés par des lignes vides.

Cela ressemble à ceci :

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```

* Takes a `first_name` and `last_name`.
* Converts the first letter of each one to upper case with `title()`.
* <dfn title="Puts them together, as one. With the contents of one after the other.">Concatenates</dfn> them with a space in the middle.

It's a very simple program.

But now imagine that you were writing it from scratch.
