In Python, this "next object in the cascade" is the class of the object (and if it is not found there it checks for the attribute in the class' superclass...). In ECMAScript the "next object in the cascade" is the prototype (and if the property is not there then the interpreter checks the prototype of the prototype...).

February 21, 2026 - ECMAScript (/ˈɛkməskrɪpt/; ES) is a standard for scripting languages including JavaScript, JScript, and ActionScript. It is best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers.

Python vs JavaScript for Pythonistas – Real Python
July 31, 2023 - Since then, there have been only a handful of releases, which looks stagnant compared to the multiple new versions of Python released each year during the same period. Notice the gap between ES3 and ES5, which lasted an entire decade! Due to political conflicts and disagreements in the technical committee, ES4 never made its way to web browsers, but it was used by Macromedia (later Adobe) as a base for ActionScript. The first major overhaul to JavaScript came in 2015 with the introduction of ES6, also known as ES2015 or ECMAScript Harmony.

Influences on ECMAScript 6
This is a list of a few ECMAScript 6 features and what their influences were: Iteration: Python (but with a modified protocol) Generators: Python · Arrow functions: CoffeeScript · const: The name comes from C++ (the latest C standard borrowed it from C++), but it behaves more like Java’s final.

Fast JavaScript parser - manual translation of esprima.js to python. Takes 1 second to parse whole angular.js library so parsing speed is about 100k characters per second which makes it the fastest and most comprehensible JavaScript parser for python out there. Supports whole ECMAScript 5.1 and parts of ECMAScript 6.

r/javascript on Reddit: What does Python do better/worse than ES6 JavaScript, esp when it comes to readability/expressiveness?
January 3, 2018 -
I don't want to use the term concise/terse, because many people take that to be a synonym for clever/confusing.
But Python is said to be a very readable language, due to syntax, whitespace rules, lack of {} etc, and is said to be 'executable pseudocode'. ES6 was a huge advance for JS and I find it a great mix of power and expressiveness.
Python:
def square(n): return n*n square2 = lambda x: x**2 def adder(x): return lambda y: x + y
ES6:
function square(x) { return x*x }
const square2 = x => x**x
const adder = x => y => x + yMaybe its because I'm used to it, but I find the JS versions easier to read/understand. Interestingly, the regular function syntax in python isn't more verbose than the lambda unlike in JS. Is there any difference between the Python version of square and square2?
I know python has things like list comprehensions and probably other things I'm not aware of that make it more powerful, and I'm curious how the 2 compare today.

Well, to be honest I find both languages quite readable but personally ES syntax is easier to understand. I'm not experienced in Python but I've read quite a lot code written in this language to convert solution to JS so there is one thing I can say about both: Pyhon code visually will look very alike whether it's written by novice or by advanced (based on code I read) In JS there is much more freedom so you can find different coding styles across the web. It's likely that it'll be harder for you to read JS code if author uses different style than you're used to.

I like to use python for data processing, and js for async things. range, list comprehension, for ... in ... loop, etc. in python makes it easy to work with strings, and lists. There are lots of libraries for data analysis. numpy allows you to do that pretty fast. I've never heard about async things in python so I guess python is not suited for that. With async/await (or promise) in JS you can write readable and short code to do async things. JS is kinda slow for CPU bound things (because it's dynamic typed), but web assembly solves that problem. And as you know, there are insane number of libraries for doing web-related things including server-side and client-side. For example, to calculate the squared sum of numbers in an array (a list in python) that are larger than 3, in js you would do arr.filter(n => n > 3).map(n => n * n).reduce((acc, n) => acc + n) In python, sum(n ** 2 for n in lis if n > 3) I think the python version is more readable yet being shorter. Also it's more memory efficient because it doesn't generate any intermediate lists or something. Python also has other useful functions to process lists (and iterables) like any(), all(), max(), min(). So I prefer python for processing a collection of data.

Python supports decorators, which are annotations placed before functions and classes to alter their behavior. The TC39 committee that controls the ECMAScript standard for JavaScript has been discussing adding decorators for many years, but they have not yet been added.
