Dans les versions précédentes de JavaScript côté navigateur / NodeJS, vous auriez utilisé des « callbacks ». Menant potentiellement à ce que l'on appelle le « callback hell ».

 *  **OkHttp now caches private responses**. We've changed from a shared cache
    to a private cache, and will now store responses that use an `Authorization`
    header. This means OkHttp's cache shouldn't be used on middleboxes that sit
    between user agents and the origin server.

 *  **TLS configuration updated.** OkHttp now explicitly enables TLSv1.2,

	// map of regular username to credentials
	iamUsersMap map[string]UserIdentity
	// map of regular username to policy names
	iamUserPolicyMap *xsync.MapOf[string, MappedPolicy]

	// STS accounts are loaded on demand and not via the periodic IAM reload.
	// map of STS access key to credentials
	iamSTSAccountsMap map[string]UserIdentity
	// map of STS access key to policy names
	iamSTSPolicyMap *xsync.MapOf[string, MappedPolicy]

Let's see that phrase by parts in the sections below:

* **`async` and `await`**
* **Coroutines**

## Asynchronous Code { #asynchronous-code }

Asynchronous code just means that the language 💬 has a way to tell the computer / program 🤖 that at some point in the code, it 🤖 will have to wait for *something else* to finish somewhere else. Let's say that *something else* is called "slow-file" 📝.
