ID: go-best-practices/comparison-true
Language: Go
Severity: Notice
Category: Best Practices
In Go, it is recommended to use the if foo
syntax, where foo
is a boolean expression, rather than comparing it explicitly to true
using if foo == true
.
Here are the reasons why if foo
is preferred:
if foo
reduces unnecessary verbosity and improves code readability. It directly expresses the condition based on the truthiness of foo
, making it easier to understand the intent of the condition without the need for an explicit comparison.foo
already evaluate to true
or false
, so comparing them explicitly to true
is redundant and unnecessary.if foo
helps prevent common mistakes, such as accidentally using =
(assignment operator) instead of ==
(equality operator) in the comparison, which would lead to a logical error.For example, consider the following code snippets:
1
2
3
if foo {
// Code block
}
1
2
3
if foo == true {
// Code block
}
Both snippets achieve the same result if foo
evaluates to true
. However, the first snippet using if foo
is preferred for its simplicity, clarity, and adherence to Go’s idiomatic style.
By using if foo
instead of if foo == true
, you can write cleaner and more readable code that takes advantage of the natural boolean evaluation in Go.
func main() {
if foo == true {
}
}
func main() {
if foo {
}
}
