    The esc_html_e() function in WordPress is an important tool for ensuring that text displayed on your website is both translated and safe for HTML output. Here's a detailed explanation and sample usage:

    Function:

    esc_html_e( string $text, string $domain = 'default' )
    

    Description:

    This function is used to display translated text that has been escaped for safe use in HTML output. This means that it will take the given text, translate it according to the specified text domain, and then escape it to prevent any HTML tags or special characters in the text from being executed as HTML. This is particularly important for avoiding cross-site scripting (XSS) vulnerabilities.

    When to Use:

    Use esc_html_e() when you want to output translated text directly into HTML, ensuring that it's safe and won't break your website's markup or introduce security vulnerabilities.

    Parameters:

    1. $text (string, required): The text string that you want to translate.
    2. $domain (string, optional): The text domain that defines the translation group. It's a unique identifier used for retrieving translated strings. The default value is 'default'.

    Behavior:

    • If there is a translation available for the text in the specified domain, it will display the translated text.
    • If there is no translation available, or if the text domain isn’t loaded, it will display the original text, but safely escaped to prevent any HTML tags from being executed.

    Sample Usage:

    Here's a simple example of how you might use esc_html_e() in a WordPress theme or plugin:

    <?php esc_html_e( 'Welcome to my website!', 'my-text-domain' ); ?>
    

    In this example:

    • 'Welcome to my website!' is the text that you want to display.
    • 'my-text-domain' is the text domain that WordPress will use to look up the translation for this text.

    This function is especially useful in themes and plugins where you want to ensure that the displayed text is both properly translated according to the site's language settings and safe from any HTML-related vulnerabilities.
