Feb 24, 2015 · Is there a function in JavaScript similar to Python's range()? All of the solutions here are referring to Python 2's range (probably because of the code example you gave). However in Python 3, the range() method returns an iterator.

Dec 4, 2024 · In Python, the range () function is commonly used to generate a sequence of numbers. But in JavaScript, there is no direct equivalent to Python's range (). In this article, we will explore how we can achieve similar functionality using a variety of approaches in JavaScript.

Oct 9, 2010 · You can easily create range() generator function which can function as an iterator. This means you don't have to pre-generate the entire array. function * range ( start, end, step = 1 ) { let state = start; while ( state < end ) { yield state; state += step; } return; };

Dec 23, 2024 · In Python, the range() function is used to generate a sequence of numbers, commonly for iteration in loops. JavaScript, however, doesn’t have a built-in range() function, but there are various ways to achieve similar functionality.

Dec 3, 2023 · The rangeJS() function provides a simple and concise way to generate sequences of numbers in JavaScript, similar to Python's range() function. It eliminates the need for additional libraries or extensions, making it a lightweight solution.

Aug 4, 2021 · If you’re not familiar with Python, range() refers to the use of the range type to create an immutable sequence of numbers. By using the Array constructor, fill and map, you could work out a ...

Aug 4, 2021 · If you’re not familiar with Python, range() refers to the use of the range type to create an immutable sequence of numbers. “The range type represents an immutable sequence of numbers and is commonly used for looping a specific number of times in for loops.” — docs.python.org

Aug 4, 2021 · So how can we make a function in JavaScript return an “immutable sequence of numbers”? Is there any way to achieve the same structure of the range() return value in JavaScript? Iterators to the rescue!

Mar 27, 2025 · Javascript lacks a direct equivalent to python's range function, but similar functionality can be achieved using generator functions, for loops, array.from (), map on arrays, or by creating a custom range function.
