Regular expression for only characters a-z, A-Z

Question

I don't know how to create a regular expression in JavaScript or jQuery.

I want to create a regular expression that will check if a string contains only characters between a-z and A-Z with any arrangement.

EDIT

When I tried to make regex

/^[a-zA-Z\s]+$/

to accept white spaces as well. It is not working. What could be the mistake?

I am testing my regular expression at JavaScript RegExp Example: Online Regular Expression Tester.

This /[^a-z]/g solves the problem.

function pangram(str) {
    let regExp = /[^a-z]/g;
    let letters = str.toLowerCase().replace(regExp, '');
    document.getElementById('letters').innerHTML = letters;
}
pangram('GHV 2@# %hfr efg uor7 489(*&^% knt lhtkjj ngnm!@#$%^&*()_');
