🆂🆀🆄🅰🆁🅴.🅹🆂

🆂🆀🆄🅰🆁🅴.🅹🆂 is a joke language created by user:PatoFlamejanteTV based on JavaScript. It is essentially just JavaScript but all of the alphabetical characters are replaced with their Unicode square equivalents, such as 🅰 being A. A downside to this is that since there isn't any lowercase letters, everything is treated as lowercase, limiting function naming such as "helloWorld", and restricting use of functions such as "toString".

Examples

Hello, World!

🅲🅾🅽🆂🅾🅻🅴.🅻🅾🅶("🅷🅴🅻🅻🅾, 🆆🅾🆁🅻🅳")

The same thing but with the "alert()" function instead.

🅰🅻🅴🆁🆃.🅻🅾🅶("🅷🅴🅻🅻🅾, 🆆🅾🆁🅻🅳")

Fibonacci

🆅🅰🆁 🅸;
🆅🅰🆁 🅵🅸🅱 = [0, 1]; // 🅸🅽🅸🆃🅸🅰🅻🅸🆉🅴 🅰🆁🆁🅰🆈!

🅵🅾🆁 (🅸 = 2; 🅸 <= 10; 🅸++) {
  // 🅽🅴🆇🆃 🅵🅸🅱🅾🅽🅰🅲🅲🅸 🅽🆄🅼🅱🅴🆁 = 🅿🆁🅴🆅🅸🅾🆄🆂 + 🅾🅽🅴 🅱🅴🅵🅾🆁🅴 🅿🆁🅴🆅🅸🅾🆄🆂
