Learn to code in different programming languages. The same line of code but in different languages:
- Variables (PHP, JavaScript, Python).
- Collections - Arrays/Lists (PHP, JavaScript, Python).
- Conditionals (PHP, JavaScript, Python).
- Loops (PHP, JavaScript, Python).
- Functions (PHP, JavaScript, Python).
- Classes (PHP, JavaScript, Python).
- Libraries (PHP, JavaScript, Python) - Geometry - Custom library (PHP, JavaScript, Python).
I use it only for didactic purposes, it does not cover all the characteristics of each language.
