JavaScript for Beginners
JavaScript as your second language after Python. Learn the syntax, types, arrays, objects, and functions by writing and running small console programs, master the functional array toolkit (map, filter, reduce), then build three pure-JavaScript mini-projects: a to-do data model, a cart calculator, and a text statistics tool.

What you'll learn
- ✓Write and run JavaScript programs that print with console.log, using variables, template literals, and the right choice of let vs const
- ✓Translate Python habits into JavaScript: dynamic types, === comparisons, truthiness, and the loop and conditional forms JS actually uses
- ✓Model data with arrays and objects, convert to and from JSON, and iterate with for...of, Object.keys, and Object.entries
- ✓Use map, filter, reduce, find, some, and every to transform data without hand-written loops
- ✓Read error messages, handle failures with throw and try/catch, and debug small programs methodically
- ✓Build pure-JavaScript mini-projects: a to-do data model, a cart calculator, and a text statistics tool
