go语言expected boolean expression found assignment missing parentheses around composite literalsyntax

In Go, the error message "expected boolean expression, found assignment" usually occurs when you mistakenly use the assignment operator (=) instead of the comparison operator (==) in a boolean expression.

For example, consider the following code snippet:

x := 5
y := 10

if x = y {
    fmt.Println("x is equal to y")
}

In this case, the line if x = y is causing the error. To fix it, you need to use the comparison operator == instead:

if x == y {
    fmt.Println("x is equal to y")
}

If you intended to use the assignment operator, you should update the code accordingly. However, keep in mind that assignments inside an if condition are not commonly used in Go, and you might need to reconsider your approach
