-## Performance considerations
-
-**Fast is Hugo's middle name** and we would not have released this feature had it not been blistering fast.
-
-This feature has been in the back log and requested by many for a long time. The development got this recent kick start from this Twitter thread:
-
-{{< tweet user="scott_lowe" id="898398437527363585" >}}
-
-Scott S. Lowe removed the "Related Content" section built using the `intersect` template function on tags, and the build time dropped from 30 seconds to less than 2 seconds on his 1700 content page sized blog.
-
-He should now be able to add an improved version of that "Related Content" section without giving up the fast live-reloads. But it's worth noting that:
-
-* If you don't use any of the `Related` methods, you will not use the Relate Content feature, and performance will be the same as before.
-* Calling `.RegularPages.Related` etc. will create one inverted index, also sometimes named posting list, that will be reused for any lookups in that same page collection. Doing that in addition to, as an example, calling `.Pages.Related` will work as expected, but will create one additional inverted index. This should still be very fast, but worth having in mind, especially for bigger sites.

+
+The `try` statement is a non-standard extension to Go's [text/template] package. It introduces a mechanism for handling errors within templates, mimicking the `try-catch` constructs found in other programming languages.
+
+[text/template]: https://pkg.go.dev/text/template
+
+## Methods
+
+The `TryValue` object encapsulates the result of evaluating the expression, and provides two methods:
+
+Err
+: (`string`) Returns a string representation of the error thrown by the expression, if an error occurred, or returns `nil` if the expression evaluated without errors.
+
+Value
+: (`any`) Returns the result of the expression if the evaluation was successful, or returns `nil` if an error occurred while evaluating the expression.
+
+## Explanation
+
+By way of example, let's divide a number by zero:
+
+```go-html-template
+{{ $x := 1 }}
+{{ $y := 0 }}
+{{ $result := div $x $y }}
+{{ printf "%v divided by %v equals %v" $x $y .Value }}
+```
+
+As expected, the example above throws an error and fails the build:
+
+```terminfo
+Error: error calling div: can't divide the value by 0
+```
+
+Instead of failing the build, we can catch the error and emit a warning:
+
+```go-html-template
+{{ $x := 1 }}
+{{ $y := 0 }}
+{{ with try (div $x $y) }}
+  {{ with .Err }}
+    {{ warnf "%s" . }}
+  {{ else }}
+    {{ printf "%v divided by %v equals %v" $x $y .Value }}
+  {{ end }}
+{{ end }}
+```
+
+The error thrown by the expression is logged to the console as a warning:
+
+```terminfo
+WARN error calling div: can't divide the value by 0
+```
+
+Now let's change the arguments to avoid dividing by zero:
+
+```go-html-template
+{{ $x := 42 }}
+{{ $y := 6 }}
+{{ with try (div $x $y) }}
+  {{ with .Err }}
+    {{ warnf "%s" . }}
+  {{ else }}
+    {{ printf "%v divided by %v equals %v" $x $y .Value }}
+  {{ end }}
+{{ end }}
+```
+
+Hugo renders the above to:
+
+```html
+42 divided by 6 equals 7
+```
+
+## Example
+
+Error handling is essential when using the [`resources.GetRemote`] function to capture remote resources such as data or images. When calling this function, if the HTTP request fails, Hugo will fail the build.
+
+[`resources.GetRemote`]: /functions/resources/getremote/
+
+Instead of failing the build, we can catch the error and emit a warning:
+
+```go-html-template
+{{ $url := "https://broken-example.org/images/a.jpg" }}
+{{ with try (resources.GetRemote $url) }}
+  {{ with .Err }}
+    {{ warnf "%s" . }}
+  {{ else with .Value }}
+    <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
+  {{ else }}
+    {{ errorf "Unable to get remote resource %q" $url }}
+  {{ end }}
+{{ end }}
+```
+
+{{% note %}}
+Hugo does not classify an HTTP response with status code 404 as an error. In this case `resources.GetRemote` returns nil.

+The `images.Mask` filter applies a mask to an image. Black pixels in the mask make the corresponding areas of the base image transparent, while white pixels keep them opaque. Color images are converted to grayscale for masking purposes. The mask is automatically resized to match the dimensions of the base image.
