Get values in a javascript array after applying regEx

Question

Well,

I've a JavaScript variable like below.

 var myVar = '<p>This is ~ro..<strong>Yes it is ~hon no?</strong>. happy halloween ~yoo. <strong>~soon</strong> Ho ~no2 ~yes Ho Ho...~jik</p>';

I want to get all words after tilde (~) in a JavaScript array using regular expression or any other method. In the above case, the array result will be something like below.

["ro","hon","yoo","soon","no","yes","jik"]

The words can be of any length. Ultimately I want to get all words after ~ in a JavaScript array variable.

~([a-zA-Z]+)

try this.grab the captures.See demo.

http://regex101.com/r/yG7zB9/15

var re = /~([a-zA-Z]+)/gm;
var str = '<p>This is ~ro..<strong>Yes it is ~hon no?</strong>. happy halloween ~yoo. <strong>~soon</strong> Ho ~no2 ~yes Ho Ho...~jik</p>';
var m;

while ((m = re.exec(str)) != null) {
if (m.index === re.lastIndex) {
re.lastIndex++;
}
// View your result using the m-variable.
// eg m[0] etc.
}

like this:

_list = myVar.match(/~(\w+)/g)

var myList = []

for( i in l){myList.push(l[i].split("~")[1])}

console.info(myList)

=======

update: change regEx to:(thanks for @nu11p01n73R)

_list = myVar.match(/~([a-zA-Z]+)/g)

small problem with the solution. you cannot use \w as the example contains ~no2 of which no2 will be matched with \w, op wants just no
