Python vs JavaScript: Numbers
Are you a full-stack Python developer? Or maybe you know Python and want to learn some differences with JS? Sometimes things are easier to remember when put in comparison, so here is a simple cheatsheet of the implementation of numbers in both languages.
Python 3 and a “modern” JS engine are assumed (V8, SpiderMonkey, JavaScriptCore).
Integers
Standard integer (Python int vs JS Number)
Built-in integers with arbitrary precision (Python int vs JS BigInt)
Floats
Python float vs JS Number
Infinity
Not-A-Number
Arithmetic operators
Formatting
Alternatives
JS
Build-in TypedArray
Nodejs C++ addons
Python
