Question

For example my string is:

"Hi @randomperson !! how are you?"

and if I have to get all characters starting from the @ to the space before the exclamation marks.

Any help is appreciated 🙂

Answer 1

Use a regular expression:

var input = "Hi @randomperson !! how are you?",
    re = /@\S+/g;

console.log(re.exec(input)[0]); // prints "@randomperson"

• The forward slashes (/) are regex literal delimiters
• @ matches a single @ character
• \S+ matches one or more non-whitespace character

That’s it.
