Do you find it inconvenient to write unnecessary JavaScript code when you just want to solve algorithm problems? Now you can solve Baekjoon problems as easily as on Programmers!

Writing a Solution Function

Write and run test cases conveniently

Tired of manually typing test cases to check results every time? Now you can write test cases along with your problem solutions and conveniently check the test results using the bananass run command!

Running a Solution File

Get started with create-banananss

Just like React's create-react-app and Next.js's create-next-app, you can start a Bananass Framework project right away with create-banananss!
