I am trying to extract all the works in a sentence that exists between two Set of words using regex

var sentence = "i would like to extract $#word1#$ ,$#word2#$ and $#word3#$"
/\$\#(.*?)\#\$/g.exec(sentence);

output is 

["$#word1#$", "word1"]

Expected output is 

['word1','word2','word3']

I tried to use match function, but I've got the array( ["$#word1#$", "$#word2#$", "$#word3#$"])

So, for your case I used function replace function. Here is code:

const subStrings = [];
sentence.replace(/\$\#(.+?)\#\$/g, (str, word) => subStrings.push(word));

console.log(subStrings);

Output subStrings: ['word1','word2','word3']

Additional information: If you want to use exec function you should take a look at this example:

var regex1 = RegExp('foo*','g');
var str1 = 'table football, foosball';
var array1;

while ((array1 = regex1.exec(str1)) !== null) {
  console.log(`Found ${array1[0]}. Next starts at ${regex1.lastIndex}.`);
  // expected output: "Found foo. Next starts at 9."
  // expected output: "Found foo. Next starts at 19."
}
