Built on Chrome’s V8 JavaScript engine, Node.js is a runtime environment that enables JavaScript to run outside the browser. This course will help you learn the fundamentals of Node.js to build portable applications.

You’ll learn about the components and build patterns of Node.js. You’ll also explore the API to learn how to create modules and write code to unique data files. Moreover, you’ll delve into the features and practices of JavaScript and build a REST API using the Express framework from scratch. This will set up authentication tokens with Passport.js and JSON web tokens, and finally build a live trivia game with Socket.IO.

By the end of this course, you’ll be equipped with the extensive knowledge to build rich and comprehensive Node.js applications running on the server with JavaScript.

Learn Node.js from Scratch

By the end of this lesson, we’ll be able to do the following:

- Use new ES6 string methods.
- Apply the template literal syntax.

# Strings

ES6 strings offer new string methods, template literals, and tagged template literals.

## New string methods

ES6 offers a few new string methods:

- The `.repeat(number)` method repeats a given string a specified number of times.
- The `.startsWith(searchString, position)` method returns `true if a string starts with `searchString`. The position` parameter specifies the start position of the search, with the default value being `0`.

- The `.endsWith(searchString, length)` method returns `true` if a string ends with `searchString`. The `length` parameter specifies the length of the string to search.

- The `.includes(searchString, position)` method returns `true` if a given string can be found in another string.

## Template literals

Template literals allow us to embed expressions in our strings using backticks (\`) and `${express}`.  This can help simplify the syntax string concatenation and create multiline strings. For example, see the code below:
