Objectives

Node JS

1. Define NodeJS as distinct from browser based JavaScript runtimes.

• In Node.js runtime, global object is where global variables are stored.

• In browsers, window objects are where global variables are stored.

• They both also their own unique accessible objects.

2. Write a program that reads in a dictionary file using node’s FS API and reads a line of text from the terminal input. The program should ‘spell check’ by putting asterisks around every word that is NOT found in the dictionary.

Git Learning

1. Use Git to initialize a repo

• Use git init to initialize a repo in your desired directory.

2. Explain the difference between Git and GitHub

• Git is a VS, Github is a remote server to push your code.

3. Given ‘adding to staging’, ‘committing’, and ‘pushing to remote’, match attributes that apply to each.

• Staging Area
  • Reserved for changes you’re ready to commit.
• Git Commit -m : Used to commit your changes/additions into the commit history - flag is used to add a message to your commit.
• git push -u origin add-my-new-file

4. Use Git to clone an existing repo from GitHub

• git clone [HTTPS url of remote repo]

5. Use Git to push a local commit to a remote branch

• git push -u origin master

6. Use git to make a branch, push it to github, and make a pull request on GitHub to merge it to master

• git branch [name of new branch]
• git add .
• git commit -m “This is my new branch”
• git push -u origin master
• follow on screen prompts to enact a pull request.

7. Given a git merge conflict, resolve it

• just choose which line you want on vscdoe.

8. Match the three types of git reset with appropriate descriptions of the operation.

• –soft : appended to reset to move our HEAD ref to the commit we specified - does not touch our code, only resets commit messages.(least dangerous!)
• –mixed : Default state of Git reset, changes are preserved but they are removed from the commit history straight to the working directory.
• –hard : Adjust head ref and totally destroy any interim code changes

9. Use Git reset to rollback local-only commits.

• git reset –hard HEAD

10. Identify what the git rebase command does

• Git Rebase : Involves changing your current branch’s base branch.

11. Use git diff to compare a local ‘staging’ branch and ‘master’ branch.

• git diff master (assuming you are on the staging branch)

12. Use git checkout to check out a specific commit by commit id

• git checkout [id]
