Javascript - Splicing strings from certain character to next character

Hopefully a basic question, as I'm a bit lost where to begin.

Pretend we have this string in JS:

var foo = "Yes, today #hello #vcc #toomanyhashtags #test we went to the park and danced"

How would I go about dynamically finding the character "#" and removing everything after until it hits a space (or in the instance of #test, until the string ends)?

ie. So the above string would read:

var foo = "Yes, today we went to the park and danced "

I had the concept to loop through the entire strings' characters and if the character === "#", delete characters until the current loop's item === " ". Is there a shorter way to do this?

Preliminary Concept:

var foo = "Hello, this is my test #test #hello";
var stripHashtags = function(x) {
    for (i=0; i < x.length; i++) {
        if (x[i] !== "#") {
            console.log(x[i]);
        }
    }
};
stripHashtags(foo);

You could also do it with a simple regex string 

foo.replace(/#[^ ]*/g, ""))

You could go about this using the indexOf() method available to strings. This returns the character location of the first occurrence of whatever you're looking for. Then use substring

var i = foo.indexOf('#');
foo = foo.substr(0,i);

foo.substr(0,foo.indexOf("#")). This can get you the required output i suppose if that's what you are looking for.
