1. Pull project from https://github.com/osneem/wordcounter-ts.git 2. Open the terminal in the project root folder 3. Use the following commands to install ts-node & necessary dependencies. npm install npm install --save @types/node npm install -g ts-node npm install -g typescript 3. To run the word frequency counter use the following command: ts-node ./src/index.ts ./src/source.txt (Please notice that './src/source.txt' is the path of a test file, which can be replaced with a path to your own desired text file!) 4. To run the Jest tests please use the following command: npm t index.test.ts (Please notice that after all of the tests have ran successfully the terminal will encounter a error: '[Error: ENOENT: no such file or directory]'. This is possibly caused by a false configuration of the testing framework, but I ran out of ideas on how to solve it.)
