The Modern JavaScript Bootcamp (2019) - Using Third-Party Libraries

The video tutorial covers how to use third-party libraries with JavaScript modules. It demonstrates installing and using the UUID library via NPM and import statements, and provides a challenge to install and use the Validator library. The tutorial emphasizes the importance of third-party libraries in saving time and effort by outsourcing common tasks. It concludes with a cleanup of the project setup.

What is the primary purpose of using third-party libraries in JavaScript projects?

• To increase the complexity of the project

• To avoid writing and maintaining common functionalities

• To make the project run faster

• To reduce the size of the codebase

Which command is used to install a library via NPM?

• npm get

• npm fetch

• npm install

• npm load

What is the purpose of the 'import' statement in JavaScript?

• To rename functions in a file

• To delete functions from a file

• Specify the version to ensure compatibility

• Install without specifying a version

• Install multiple versions simultaneously

What should you do after finishing with a third-party library you no longer need?

• Leave it installed for future use

• Uninstall it using NPM

• Delete it manually from node_modules

• Ignore it

What is a key advantage of using third-party libraries in JavaScript projects?

• They require less documentation

• They increase the size of the project
