```javascript
function validateEmail(email) {
// Regular expression to match email patterns
var emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
// Check if the email matches the pattern
if (emailRegex.test(email)) {
return true; // It's a valid email address
} else {
return false; // It's not a valid email address
}
}
// Usage example
var email = "[email protected]";
if (validateEmail(email)) {
console.log("Valid email");
} else {
console.log("Invalid email");
}
```
In the code above, the `validateEmail` function takes an email address as an argument and uses a regular expression to check if it matches the pattern `[^\s@]+@[^\s@]+\.[^\s@]+`. This regular expression ensures that the email has at least one character before the @ symbol, at least one character between the @ symbol and the dot, and at least one character after the dot. If the email matches the pattern, the function returns `true`, indicating a valid email address. Otherwise, it returns `false`.
You can test different email addresses using this code and customize the regular expression if needed to suit your specific validation requirements."
