Does JavaScript support array/list comprehensions like Python?

Question

I\'m practicing/studying both JavaScript and Python. I\'m wondering if Javascript has the equivalence to this type of coding.

I\'m basically trying to get an array

Answer 1

It does have a poor mans version

const string = '1234-5'

const forbidden = '-'

print([int(i) for i in str(string) if i not in forbidden])
const result = string.split('').filter(char => char !== forbidden);
console.log(result)

In JS you can only iterate over single elements in array, so no extraction of multiple entries at a time like in Python.

For this particular case you should use a RegExp to filter the string though.
