Objectives

Running JS Locally

• Match the commands ls, cd, pwd to their descriptions

  • ls : lists all files and subdirectories in the current directory.
  • cd [path] : changes the current directory to the directory specified by the path argument.
  • pwd : The present working directory command lists the path from your current location starting from root.

• Given a folder structure diagram, a list of ‘cd (path)’ commands and target files, match the paths to the target files.

  Referencing the above file structure - if you are currently in the Notes directory what would running the command pwd return?

  • /Desktop/Homework/Notes

• Use VSCode to create a folder. Within the folder create a .js file containing console.log(‘hello new world’); and save it.

  • Manually:
  • To manually create a folder in VSCode, click the ‘new folder’ button.

  • To create a file within that folder, click on the folder to enter it, and then selected ‘new file’ to create a file (you can change the type of file it is by appending the correct ext. type)

  • Via Terminal
  • Use mkdir to create a folder.
  • cd to your new folder.
  • use touch command to create a js file.

  • use code . command to open VSCode with your pwd.

• Use node to execute a JavaScript file in the terminal
  • Type in node <fileName.js> into your terminal to execute.
