RegEx - Parse through string for specific words

I'm looking to parse through a string and find all the handles (@name) and push them each into one array (without the @ though) so I can loop through them (with forEach) and send them each an alert. Each handle is separated by a space.

Message example

try

let str= "Here @ann and @john go to @jane";

let m= str.match(/@\w+/g).map(x=>x.replace(/./,''));
                              
m.forEach(x=> console.log(x));

You can use also positive lookbehind regexp but it is not supported by firefox yet (but it is part of ES2018):

let str= "Here @ann and @john go to @jane";

let m= str.match(/(?<=@)\w+/g);

m.forEach(x=> console.log(x));

where (?<=@)\w+ match word which start after @ (excluding this char - positive lookbehind)

Try This:

var str= "Here @ann and @john go to @jane";
var patt = /@(\w+)/g;

while ( (arr = patt.exec(str)) !== null ) { console.log(arr[1]); }

You can combine match to extract names and slice to remove @:

str = "@JohnSmith @DylanThompson Hey guys";
let arr = str.match(/@\w+/g).map(e=>e.slice(1));
console.log(arr);

You can capture @followedByName and than replace @

let str = `@someName hey @someMoreNames`

let op = str.match(/(^|\s)@\w+/g).map(e=>e.trim().replace(/@/g,''))

console.log(op)

If you just need to extract the users from a tweet, you can use the following regex:

/@([a-zA-Z0-9]+)/g

For example: 

var string = '@JohnSmith @DylanThompson Hey guys!';
var numberPattern = /@([a-zA-Z0-9]+)/g;

var res = string.match(numberPattern);

console.log(res);

This would spit out:

["@JohnSmith", "@DylanThompson"]
