Regex Not Capturing Email Addresses with Subaddressing in JavaScript - implementing Plus Sign
I'm testing a new approach and I'm writing unit tests and I'm trying to debug I'm stuck on something that should probably be simple... I'm trying to validate email addresses in JavaScript, specifically ones that can include subaddressing (like `user+label@example.com`). However, my current regex fails to capture these correctly. I want to allow for the `+` sign followed by alphanumeric characters before the `@` symbol, but I'm running into issues with matching the entire email format accurately. Here's the regex I've been using: ```javascript const emailRegex = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/; ``` When I test it with emails like `test+123@gmail.com` or `user.name+test@example.org`, it doesn’t match, which is unexpected because the plus sign should be allowed before the domain. I’ve also tried altering the regex to include the plus sign explicitly: ```javascript const emailRegex = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/; ``` However, I still face issues with valid examples, while it seems to incorrectly match other strings that shouldn't be valid emails. The failed matches return `null` when using `.match(emailRegex)`. Does anyone have suggestions on how to modify this regex to correctly capture emails with subaddressing while ensuring other invalid formats are still rejected? Any help would be appreciated! Thanks in advance! I'm developing on Debian with Javascript. I'm on Windows 10 using the latest version of Javascript. Any ideas how to fix this? Has anyone dealt with something similar?
