How to split a string on spaces?

Question

JavaScript

There is a line like this:

"слово_слово_____слово___" //для наглядности пробелы заменены на подчеркивания

That is, there can be one or more spaces after each word.

How to get an array of words?

trim() - will remove spaces around the edges,
and inside you need to replace sequences of spaces with spaces, so that later you can split them using split()

Answer 1

str.trim().replace(/[ ]+/g, ' ').split(' ')
or
str.split(' ').filter(i => !!i)
