In the provided benchmark, the focus is on measuring the performance of two different methods for converting a JavaScript URL
object into its string representation. The two options being compared are:
.toString()
Method from the URL
objectString()
function for type conversionThe benchmark tests how quickly each of these options can convert a URL object, specifically new URL("http://localhost/?search=term")
, to a string, by executing each method 100 times in a loop.
.toString()
method
.toString()
method is purpose-built for the URL
object. It is highly optimized and typically more efficient for this specific task.URL
objects.String()
function
String()
can be used with various types of objects beyond just URL
, which may suggest versatility in different contexts.URL
is being converted to its string representation.The results from the benchmark show:
.toString()
has an execution rate of approximately 106,844.67 executions per second.String()
has a significantly lower execution rate of approximately 62,308.50 executions per second.This indicates that the .toString()
method is about 1.71 times faster than using the String()
function for this specific operation.
.toString()
is explicit about its purpose regarding URL
objects.URL
object.Using Template Literals: For some cases, developers may opt to use template strings like `${url}`
, which relies on the default string conversion behavior but would generally be less optimized and less clear in intention when converting a URL
.
Manual String Construction: Developers could parse the components of the URL
object manually (e.g., url.protocol + '//' + url.host + url.pathname
) but this approach would likely introduce potential errors and increase complexity in cases where the URL is intricate.
Third-Party Libraries: If more functionality is needed (e.g., URL manipulation, validation), libraries like query-string
or URL.js
could be used, but for simple string conversions, these would add unnecessary overhead.
In summary, the benchmark illustrates optimal ways to handle converting a URL
object to a string, with .toString()
proven to be the superior method in terms of performance for this particular scenario.
