Understand Node.js Buffers


In this lesson, we cover the Node.js Buffer object in detail. Not only will you learn that the buffer object is a reference to a memory space outside of the V8 engine, but you will learn practical methods to access it, modify it, and convert it to standard Javascript objects that can be used by your code. Examples and discussion are provided for using the toString() method, determining the byte length of the buffer, writing to a buffer, how to avoid truncating data, comparing buffers for equality using both compare() and equals(), and copying buffers using slice().
