You can use a regex to test if a string contains a special character or not. For example, using Regex test() function returns true if special characters present else returns false.

let specialChars =/[`!@#$%^&*()_\-+=\[\]{};':"\\|,.<>\/?~ ]/;

console.log(specialChars.test("String with speci@l ch@ract&r$"));
console.log(specialChars.test("String with spaces"));
console.log(specialChars.test("StringWithoutSpaces"));
