Open Source TypeScript Algorithms

Simply click Sign in to LeetCode in the LeetCode Explorer will let you sign in with your LeetCode account. By clicking the button btn_endpoint at the explorer's navigation bar, you can switch between different endpoints. The accounts of different endpoints are not shared. Please make sure you are using the right endpoint. The extension will use leetcode.com by default. Directly click on the problem or right-click the problem in the LeetCode Explorer and select Preview Problem to see the problem description. Select Show Problem to directly open the file with the problem description. The extension supports 5 editor shortcuts (aka Code Lens). To manage your LeetCode sessions, just clicking the LeetCode: *** at the bottom of the status bar. You can switch between sessions or create, delete a session.

Lago is a study-oriented library of classic data structures and algorithms implemented in JavaScript with an emphasis on readability and learning. Instead of aiming to be a production runtime, it serves as a reference you can step through to understand how arrays, stacks, queues, linked lists, trees, heaps, graphs, and sorting/searching routines actually work. The implementations favor clarity over micro-optimizations, making them approachable for learners who are new to algorithmic thinking or coming from non-CS backgrounds. Because the code is idiomatic JavaScript, it also helps front-end engineers strengthen fundamentals without switching languages. The repository’s structure lets you browse topic by topic and compare trade-offs such as time versus space complexity. It’s a handy companion to interview prep lists: after reading a concept, you can open the matching Lago implementation and trace it line by line.
