Can you guide me on defining the return type for this function?
function mapArrayToObjByKeys(range: [string, string], keys: { start: string; end: string }) {
return {
[keys.start]: range[0],
[keys.end]: range[1]
}
}
For instance:
mapArrayToObjByKeys(['a', 'b'], { start: 'beginning', end: 'ending' })
I'm looking for intelligent code suggestions like 'beginning' and 'ending' in vscode.
In cases where keys are flexible and not fixed, you can specify the return type as:
type dynamicObjReturnType = {
[key: string]: string;
}
You can then use it in a function like this:
function createDynamicObject(keys: { key1: string; key2: string }): dynamicObjReturnType {
return {
[keys.key1]: 'value1',
[keys.key2]: 'value2'
}
}
If the keys are known to be fixed as 'key1' and 'key2', they can be directly included in the type definition:
function createFixedObject(keys: { start: 'key1'; end: 'key2' }): dynamicObjReturnType {
return {
[keys.start]: 'value1',
[keys.end]: 'value2'
}
}
type fixedObjReturnType = {
key1: string;
key2: string;
}
