The core concepts — variables, loops, functions, and objects — are the same, but the way you write them changes. Below is a quick comparison to help you shift your mindset: Variables In JavaScript, you use , , or : In Python, you don’t use keywords — just assign directly: Semicolons and Curly Braces In JavaScript, you use semicolons and : In Python, you drop semicolons and use indentation instead: Indentation (usually 4 spaces) is mandatory and defines code blocks. Functions JavaScript functions: Python functions use : Printing Output JavaScript: Python: Arrays vs Lists JavaScript arrays: Python lists: Objects vs Dictionaries JavaScript objects: Python dictionaries: Quick Takeaway Think of Python as JavaScript without semicolons or braces, and with cleaner, indentation-based blocks . Once you get used to the syntax, the logic stays the same.
