Converting an array of strings to IDropdownOption in TypeScript and vice versa

In my TypeScript code snippet, I have defined two functions: getstringArray1DropdownOption and getstringArray2DropdownOption to handle dropdown options.

function getstringArray1DropdownOption(stringArray1Text: string): IDropdownOption {
    return {
        text: stringArray1Text,
        value: getstringArray1Value(stringArray1Text)
    };
}

function getstringArray2DropdownOption(stringArray2Text: string): IDropdownOption {
    return {
        text: stringArray2Text,
        value: stringArray2Text
    };
}

export const StringArray1[] = [
    "string1",
    "string2",
    ]
    .map(getStringArray1DropdownOption);

export const StringArray2: IDropdownOption[] = [
     "string3"
    ]
    .map(getStringArray2DropdownOption);

Now, I am looking to refactor the implementation of stringArray1 and stringArray2. I want to convert them from the previous format:

var options = ["str1", "str2", ..].map((str) => makeDropDownOption(str));

To a new format that separates definition and mapping like this:

var options = ["str1", "str2", ..];
var dropdownOptions = options.map((str) => makeDropDownOption(str));

I need help with the best approach to achieve this as I am encountering type errors during the process. Any suggestions would be appreciated.

Answer №1

After simplifying stringArray1 and stringArray2 to basic string arrays, all that's left to do is:

let formattedDropdownOptions1 = stringArray1.map(getFormattedDropdownOption);
let formattedDropdownOptions2 = stringArray2.map(getFormattedDropdownOption);
