JS Crossword: When the Clue Is a JavaScript Eval
Introduction
In the world of web development, JavaScript is ubiquitous and continues to inspire innovative challenges. JS Crossword is one such challenge, a crossword puzzle where each clue is a JavaScript eval of its answer. This original concept attracts those who love to explore the lesser-known corners of JavaScript.
An Innovative Concept
JS Crossword offers a unique format: each answer to a clue is evaluated using the eval() function. For instance, the clue "7" could be solved by the JavaScript expression "3+4". This approach requires a deep understanding of some JavaScript features, sometimes little-known or even "cursed".
Game Rules
To solve this puzzle, you can use the following characters: A-Za-z0-9!"()*+-./[]{}. No spaces, commas, or semicolons are allowed. Answers must be English words, case-sensitive, and will be evaluated within a sandbox via eval()`.
JavaScript and Its Quirks
JavaScript is famous for its quirks. Behaviors like [object Object] being solved by []+{} illustrate these oddities. JS Crossword leverages these behaviors to offer a captivating and sometimes perplexing challenge.
Using Resources
Although the challenge is significant, it's possible and recommended to use resources like DevTools, MDN, or even online searches. This not only helps with progressing through the puzzle but also enhances one's JavaScript skills.
A Community Puzzle
