Make a simple word wrapper

(Note: This is my first ever code golf question, but as far as I can tell, nobody else has done exactly this, so I should be good.)



Your task is to make a program or function that takes in a string s and an integer n, and returns or outputs that text wrapped into multiple lines. Each word must be wholly on a line; i.e. no words split in the middle.



Example:



s = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eget erat lectus. Morbi mi mi, fringilla sed suscipit ullamcorper, tristique at mauris. Morbi non commodo nibh. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Sed at iaculis mauris. Praesent a sem augue. Nulla lectus sapien, auctor nec pharetra eu, tincidunt ac diam. Sed ligula arcu, aliquam quis velit aliquam, dictum varius erat." 
n = 50

output:
Lorem ipsum dolor sit amet, consectetur adipiscing
elit. Sed eget erat lectus. Morbi mi mi, fringilla
sed suscipit ullamcorper, tristique at mauris.
Morbi non commodo nibh. Pellentesque habitant
morbi tristique senectus et netus et malesuada
fames ac turpis egestas. Sed at iaculis mauris.
Praesent a sem augue. Nulla lectus sapien, auctor
nec pharetra eu, tincidunt ac diam. Sed ligula
arcu, aliquam quis velit aliquam, dictum varius
erat.


Your output can be an array of strings or a single string with line breaks. Also, you can assume n will be above 10, so don't worry about dealing with weird cases.



Standard I/O rules apply, and standard loopholes are prohibited.



Since this is code-golf, the shortes solution in bytes wins.



Here is an example program in Python that would work.

Vim, 15 bytes/keystrokes



DJ:se tw=<C-r>"
gq_


A text formatting question? I know just the tool for the job! And it even has my name in the first two keystrokes :D



<C-r> means ctrl-r.



This could ever so slightly shorter in V, but I prefer answering in vanilla vim for answers that really show off how concise vim can be for the right challenge. And the difference is so small anyway.



This could also be the following for 15 bytes as well:



:se tw=<C-r><C-w>
ddgq_

    Takes input as (string)(n).





    s=>n=>s.split` `.map(w=>(r+w)[n-1]?(o+=r+`
    `,r=w):r+=r?' '+w:w,o=r='')&&o+r

        Bash, 7 bytes



        fmt -$n


        Input taken from stdin, line width stored in a variable n (is this allowed?).



        This gives the correct answer on my Mac:



        $ echo "$s" | fmt -$n
        Lorem ipsum dolor sit amet, consectetur adipiscing
        elit. Sed eget erat lectus. Morbi mi mi, fringilla
        sed suscipit ullamcorper, tristique at mauris.
        Morbi non commodo nibh. Pellentesque habitant
        morbi tristique senectus et netus et malesuada
        fames ac turpis egestas. Sed at iaculis mauris.
        Praesent a sem augue. Nulla lectus sapien, auctor
        nec pharetra eu, tincidunt ac diam. Sed ligula
        arcu, aliquam quis velit aliquam, dictum varius
        erat.

                                          If this is an answer to a challenge…




                                          • …Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.


                                          • …Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one.
                                            Explanations of your answer make it more interesting to read and are very much encouraged.


                                          • …Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.



                                          More generally…




                                          • …Please make sure to answer the question and provide sufficient detail.


                                          • …Avoid asking for help, clarification or responding to other answers (use comments instead).






                                          Some of your past answers have not been well-received, and you're in danger of being blocked from answering.

                                          • Please be sure to answer the question. Provide details and share your research!

                                          But avoid



                                          • Asking for help, clarification, or responding to other answers.
