Understanding Template Literals in JavaScript
The 2015 edition of the ECMAScript specification (ES6) added template literals to the JavaScript language. Template literals are a new form of making strings in JavaScript that add a lot of powerful new capabilities, such as creating multi-line strings, using placeholders to embed expressions in a string, and parsing dynamic string expressions with tagged template literals. In this article, you will go over the differences between single/double-quoted strings and template literals.
Using Buffers in Node.js
A buffer is a space in memory (typically RAM) that stores binary data. In Node.js, we can access these spaces of memory with the built-in Buffer class. Buffers are useful when using JavaScript to interacting with binary data, usually at lower networking levels. In this tutorial, you will use the Node.js REPL to create buffers, read from buffers, write to and copy from buffers, and use buffers to convert between binary data and data encoded with ASCII and UTF-8.
