GoLang == true已评估，但未使用

Question

Inside the code, I try to do some operations

is_html := false;

// Check, if HTMl is exist 
for i := 0; i < len(modules_arr); i++ { 
    if modules_arr[i] == "html" { is_html := true }

}

if is_html ==true
{
    fmt.Printf("%v", "asdasd")
}

But I get an error:

./api.go:26: missing condition in if statement
./api.go:26: is_html == true evaluated but not used
Error: process exited with code 2.

Answer 1

if statements needs the { on the same line in go

This means you cannot do

if is_html ==true
{
    fmt.Printf("%v", "asdasd")
}

The correct code is

if is_html ==true {
    fmt.Printf("%v", "asdasd")
}
