    PR Review

    ⏱️ Estimated effort to review [1-5]

    3, because the PR involves changes in error handling and selector strategies which are crucial for functionality but are not overly complex. Reviewing these changes requires a good understanding of the existing implementation and the impact of these changes on it.

    🧪 Relevant tests

    No

    🔍 Possible issues

    Possible Bug: The use of escapeQuotes function is assumed but not defined or imported in the provided diff. This might lead to runtime errors if not properly handled.

    Error Handling: The error message "Cannot locate option with value: ${value}" uses template literals, but it's not clear if the surrounding function supports template string interpolation as expected in JavaScript.

    🔒 Security concerns

    No

    Best practice
    Improve the safety and readability of XPath string construction.

    The string concatenation in the XPath expression might lead to incorrect queries or
    potential injection issues if not properly escaped. Use template literals for better
    readability and safety.

    javascript/node/selenium-webdriver/lib/select.js [227]

    -let options = await this.element.findElements(By.xpath('.//option[@value = ' + escapeQuotes(value) + ']'))
+let options = await this.element.findElements(By.xpath(`.//option[@value = ${escapeQuotes(value)}]`))
    Simplify the check for empty options array to enhance readability.

    Instead of manually throwing an error for empty options, leverage JavaScript's built-in
    functionality or simplify the check to enhance code readability and performance.

    javascript/node/selenium-webdriver/lib/select.js [438-439]

    -if (options.length === 0) {
+if (!options.length) {
   throw new Error(`Cannot locate option with value: ${value}`)
 }
    Enhancement
    Clarify the error message when a null element is provided to the constructor.

    To ensure the error message is consistent and clear, consider rephrasing it to specify
    that the element is expected to be a WebElement representing a tag.

    javascript/node/selenium-webdriver/lib/select.js [150]

    -throw new Error(`Element must not be null. Please provide a valid <select> element.`)
+throw new Error(`Invalid element: The provided element is null. Please provide a WebElement representing a <select> tag.`)
    Ensure the element provided to the constructor is a valid WebElement.

    Add a check to ensure that the element provided to the constructor is indeed a WebElement,
    enhancing robustness and error handling of the constructor.

    javascript/node/selenium-webdriver/lib/select.js [153]

    +if (!(element instanceof WebElement)) {
+  throw new TypeError('The provided element is not a valid WebElement.');
+}
 this.element = element
    Security
    Use template literals for consistent and safe embedding of user input in XPath queries.

    Ensure the use of escapeQuotes function is consistent across all instances where user
    input is embedded in XPath queries to prevent injection attacks.

    javascript/node/selenium-webdriver/lib/select.js [379]

     const optionElement = await this.element.findElement(
-  By.xpath('.//option[normalize-space(.) = ' + escapeQuotes(text) + ']'),
+  By.xpath(`.//option[normalize-space(.) = ${escapeQuotes(text)}]`)
 )
