How to connect to an API (with JavaScript)?
The following steps outline the process for connecting to an API using JavaScript: 1. Create a fetch request using the ` fetch() ` method of the JavaScript window object. This request should contain the required API endpoint, method (e.g. GET, POST, etc.) and any needed parameters or data. 2. Pass the created fetch request to the API using the `.then()` method and optionally specify an error handler using the `.catch()` method. 3. Parse the response returned from the API using the `.json()` method, and store that data into a variable. 4. Access the values returned from the API by referencing the stored data. 5. Optionally, handle errors generated from the API by calling your error handler function created in step 2.

How does the Java virtual machine handle a direct byte buffer?
The Java Virtual Machine (JVM) allocates and manages direct byte buffers to provide efficient data storage and retrieval for both native code and Java programs. Whenever data needs to be manipulated via a direct buffer, the JVM's native I/O routines will access the buffer and read or write it as necessary. They support types like ByteBuffer, CharBuffer, IntBuffer and many more. The JVM also takes care of mapping the buffer on the non-heap memory in order to improve performance.


Is there an empirical correlation between viscosity and temperature?
