How to Initialize Go Function Fields Without an 'Unresolved Reference' Error?

Initialize Function Fields

Problem:

In Go, how can you initialize a function's fields when calling the function, without encountering the 'Unresolved reference error'?

Answer:

Go does not support specifying parameter names when calling a function. Instead, provide values in the expected order. However, there are two viable solutions:

Using a Struct:

1. Create a Struct:

type Params struct {
    name, address, nick string
    age, value          int
}

2. Modify the Function to Accept a Struct:

func MyFunction(p Params) {
    // perform some operations
}

3. Call the Function with a Struct:

func main() {
    MyFunction(Params{
        name:    "Bob",
        address: "New York",
        nick:    "Builder",
        age:     30,
        value:   1000,
    })
}

Using a Helper Function:

1. Create a Helper Function:

func MyFunction2(p Params) {
    MyFunction(p.name, p.address, p.nick, p.age, p.value)
}

2. Call the Helper Function:

MyFunction2(Params{
    name:    "Bob",
    address: "New York",
    nick:    "Builder",
    age:     30,
    value:   1000,
})

By using a struct or a helper function, you can initialize a function's fields by providing values to the specified parameters.
