Use `strings.Diff` to compare two strings and render a highlighted diff:
|
|||
|
|||
```go-html-template
|
|||
{{ $want := `
|
|||
<p>The product of 6 and 7 is 42.</p>
|
|||
<p>The product of 7 and 6 is 42.</p>
|
|||
`}}
|
|||
|
|||
{{ $got := `
|
|||
<p>The product of 6 and 7 is 42.</p>
|
|||
<p>The product of 7 and 6 is 13.</p>
|
|||
`}}
|
|||
|
|||
{{ $diff := strings.Diff "want" $want "got" $got }}
|
|||
{{ transform.Highlight $diff "diff" }}
|
|||
```
