Split string from sentence into newline in javascript

Question

I have a string:

"Community - Moderate Environment - Minor Financial - Major Health & Safety - Extreme "

I want to split this string into:

Community - Moderate

Environment - Minor

Financial - Major

Health & Safety - Extreme

its like give newline after one category,

how do I get that

I try to split:

var t = Community - Moderate Environment - Minor Financial - Major Health & Safety - Extreme

t.split('-')

after that I don't know what can I do

split creates an array. Do you actually want an array, or just a new string with newlines? — CertainPerformance

this is not a question following the stackoverflow guidelines. it does not show an attempt of solving this yourself. — GottZ

That's kind of impossible. What should Word1 - Word2 Word3 Word4 - Word5 split into? It can either be Word1 - Word2 Word3 and Word4 - Word5 or Word1 - Word2 and Word3 Word4 - Word5 — Roberto Zvjerković

Use .replace instead of split to replace the word after a - with that word concatenated with a newline:

const str = "Community - Moderate Environment - Minor Financial - Major Health & Safety - Extreme ";
console.log(str.trim().replace(/(- \w+) +/g, '$1\n'));

The regular expression

/(- \w+) +/

captures a dash, followed by a space, followed by word characters, in a group. Then, it matches spaces, so that the whole match can be replaced with the first capture group - effectively replacing the spaces with newline characters.
