How to write words in an array?

I want the words you typed in input[type="text"] record into an array and display in a paragraph tag but when I enter to input any word and press the button is saved here is [""].

Where I make a mistake ?

tell me, if the words be separated by a space how to record them separately in an array? - Michaela_OKon commented on March 20th 20 at 11:57
@augustus_Doyle26, here:
// here everything is clear )))
var bt = document.getElementById('btn').onclick = method;
var pr = document.getElementById('paragraph');
var inp = document.getElementById('input');

// create an array drive, in which we put value
var arr = [];

function method (){
 // get the text entered in the input. if you do so as you have
 // (outside handler) then the variable will be void (the value that 
 // was input at the time of application to inp.value
 const text = inp.value;

 // here we're just splitting a string into words. separator 
 // is \s+ - any whitespace character (space, tab, 
 // carriage return, a newline)
 // repeated 1 or more times. the output will be an array of words
 const list = text.split(/\s+/);

 // insert the array of words into the array drive
 // here's the trick, the ellipses will turn the array list into a list 
 // parameters. Ie the same record as if we 
 // indicated arr.push(list[0] list[1], etc to the end of the array);

 // combine an array of drive in the line 
 // delimiters of elements is ", "
 const result = arr.join(", ");

 // insert the string with the result in paragraph
 pr.innerText = result;

 // reset the text input
 inp.value = "";

what is ... three points ?

this operator ES6 Spread

and be sure whether its availability ?

If you don't need to store in array the results of the previous input, then you are quite suitable variant from @Zelma_Daugherty.

If the previous value is necessary to maintain, adding the newly introduced words but you don't want to use the Spread operator, you can replace this:


or this:
arr.concat(list); - Martine.Adams65 commented on March 20th 20 at 12:09
