Commenting "null" value in javascript

Question

What is the right way to comment null value in javascript? For example:

/**
 * Hides an element.
 * @param {String} id - element id (can be {@code null}).
 * @returns {undefined}.
 */
function hide(id) {

    if (id !== null) {
        document.getElementById(id).style.visibility = 'hidden';
    }
}

But the tag {@code null} not working...

Answer 1

Just came across the same issue myself and found that using backticks (``) did the trick for me. Using the JSDoc comment used in your example, it should look like:

/**
 * Hides an element.
 * @param {String} id - element id (can be `null`).
 * @returns {undefined}.
 */
