Javascript – splitting sentences of a number list by its numbers

i am quite new to javascript,
Lets say i have this:

const text = "1. foo. 2. bar. 3. baz";

this is a json returned from calling api,
is there any way to add a new line after a number index so that i can look like this when output:

  1. foo.
  2. bar.
  3. baz.

i want to make it like a

i tried to split by "." but it does not work and repeatedly giving

1.foo
1.foo
3.baz
3.baz

is there any way to do that?

    You could use a regex and replace all numbers with a white spaces before and a dot after with a new line + the match characters. Also you would probably want to trim the prefix white spaces:

    const text = "1. foo. 2. bar. 3. baz.";

console.log(text.replace(/(?<!^)s*(d+.s+)/g, 'n$1'));

    The OP’s required result can be achieved by a simple replace task which …

    • does (globally) replace "each dot followed by at least one space and at least one digit" (/.s+(d+)/g) by "a dot, a new line and the captured digit sequence" ('.n$1').
    console.log(

  '1. foo. 2. bar. 3. baz.'

    // - see ... [https://regex101.com/r/3LnxBQ/1]
    // - replace each dot followed by at least one
    //   space and at least one digit by a dot, a
    //   new line and the captured digit sequence.
    .replace(/.s+(d+)/g, '.n$1')
);
