I'm trying to convert a string like 'Some\nexample\nstring' into an array like ['Some', '\n', 'example', '\n', 'string']
But it's insane that I have to do this:
let words = text.replace('\n', ' \\n ').split(/\s/);
words = words.map(it => {
if (it === '\\n') return '\n'
else return it
})
// result: ['Some', '\n', 'example', '\n', 'string']
Because this doesn't work:
const words = text.replace('\n', ' \n ').split(/\s/);
// result: ['Some', '', '', 'example', 'string']
Nor this:
const words = text.replace('\n', ' \\n ').split(/\s/);
// result: ['Some', '\\n', 'example', 'string']
Nor this:
const words = text.replace('\n', ' \\\n ').split(/\s/);
// result: ['Some', '\\', '', 'example', 'string']
What gives?
Here is a string match approach. We can alternatively match groups of whitespace or non whitespace characters.
var input = 'Some\nexample\nstring';
var parts = input.match(/\s+|\S+/g);
console.log(parts);If you want the split pattern to be included in the result, capture it, e.g.
console.log(
'Some\nexample\nstring'.split(/(\n)/)
)
