Change references from Jasmine to Jest in main readme

Update README with Jest specific language. Update some spec files with new syntax

update tests, multiple exercises

.gitignore: Added package-lock.json, package.json that were used when I ran code-blocks over the tests.

Standardised function declaration calls across exercises

fix typo in caesar.spec.js

Ignoring package-lock.json, package.json

Backtrack on .gitignore modification, add instructions to readme

move files from testing repo to this repo

Typo fixes, remove duplicate exercise folder

Remove solution from non-solution branch

Minor grammatical fixes

added trailing semicolon to all function and module exports

Fix words caught by search/replace action.

remove doubled semicolon.

Correct words caught by search/replace action.

Add missing semicolon.

Add .DS_Store to .gitignore

multiple files: Added a blank line at the end of each file

Ignore generator-exercise when linting exercise files

Update exercise number of each exercise

Update exercise number

 ## How To Use These Exercises
 Before you start you should have a few things installed on your machine:
 1. NPM. To check if you have NPM installed, type `npm --version` in your terminal. If you get back `Command 'npm' not found, but can be installed with:`, do NOT follow the instructions in the terminal to install with `apt-get`. (This causes permission issues.) Instead, install Node with NVM by following the instructions [here](https://github.com/TheOdinProject/curriculum/blob/master/foundations/installations/installing_node.md).
-2. Jasmine. Jasmine is a testing framework for JavaScript. Type `jasmine -v` to check for it. If you need to install it, type `npm install -g jasmine` to do so.
-3. A copy of this repository. Copies of repositories on your machine are called clones. If you need help cloning, you can learn how [here](https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/cloning-a-repository)
+2. Jest. Jest is a testing framework for JavaScript. To install it, type `npm install --save-dev jest`. We use `--save-dev` here to specify this module is for development purposes only.
+3. A copy of this repository. Copies of repositories on your machine are called clones. If you need help cloning, you can learn how [here](https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/cloning-a-repository).
 
-Each exercise includes 3 files: a markdown file with a description of the task, an empty (or mostly empty) JavaScript file, and a set of tests. To complete an exercise, you'll need to go to the exercise directory with `cd exerciseName` in the terminal and run `jasmine exerciseName.spec.js`. This should run the test file and show you the output. When you first run a test, it will fail. This is by design! You must open the exercise file and write the code needed to get the test to pass. Some of the exercises have test conditions defined in their spec file that are defined as 'xit' compared to 'it'. This is purposeful. After you pass your first 'it', you will change the next 'xit' to an 'it' and test your code again. You'll do this until all conditions are satisfied.

+
+**Note**: Due to the way Jest handles failed tests, it may return an exit code of 1 if any tests fail. NPM will interpret this as an error and you may see some `npm ERR!` messages after Jest runs. You can ignore these, or run your test with `npm test exerciseName.spec.js --silent` to supress the errors.
 
 The first exercise, `helloWorld`, will walk you through the process in-depth.

+Implement the legendary Caesar cipher:
 
 > In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be replaced by A, E would become B, and so on. The method is named after Julius Caesar, who used it in his private correspondence.

 ## Hints
 - You should return the whole person object, but the tests mostly just check to make sure the name is correct.
 - this can be done with a couple of chained array methods, or by using `reduce`.
 - One of the tests checks for people with no death-date.. use JavaScript's Date function to get their age as of today.
