Analyzing DNA
A Learning TypeScript > Arrays 🥗 appetizer project. You'll practice writing single- and multi-dimensional arrays, along with their corresponding type annotations.
Hello! You're a research biologist at the Strongly Typed Institute of Biochemistry. We've got a great task for you today: analyzing sequences of DNA to find mutations!
Don't worry, you won't have to draw on your vast experience of biochemical studies. We reduced the DNA information to arrays of single-character strings. Your task is to write TypeScript functions that take in DNA and return the differences. We'll walk you through each of the functions you need to write.
Setup
If you haven't yet, set up the github.com/LearningTypeScript/projects repository locally.
shell
shell
Open your editor in this project's directory:
shell
shell
In one terminal, run the TypeScript compiler via the tsc script within whichever step you're working on.
For example, to start the TypeScript compiler on the first step in watch mode:
shell
shell
In another terminal, run Jest via the test script on whichever step you're working on.
For example, to start tests for the first step in watch mode:
shell
shell
Note: your terminal should be in the
analyzing-dnadirectory, not the root repository's directory.
Steps
Notes
- Please solve these with
forloops, not fancy.map/.reduceshenanigans or with npm libraries.- For bonus points, you can try making versions of all the steps that only use array methods instead of
forloops!
