Mixing
Typescript: Accessing the properties of a key value pair in typescript
0
I have a key value pair object in typescript.
const data = {INTERNAL:[372042],EXTERNAL:[332244]};
The above is not a map, but I want to iterate over its keys and use it in a switch case pattern.
mapData(data: { key: string; value: Array<number> }):void{
switch(data[key]) {
case 'INTERNAL':
console.log('this is Internal data' =+data[value];
break;
case 'EXTERNAL':
console.log('this is External data' =+data[value];
break;
default:
}
}
data[key] or data[value] is throwing an error saying key/value is not existing'.
What is the correct way to access the data.

You've tagged this question withfor-loopbut there is notforloop in the code. Please edit your question to include a Minimal, Complete, and Verifiable example that demonstrates the issue you are seeing.

Still not reproducible, since you don't show how you're callingmapData. Note that if you're callingmapData(data), it should show a compile error, sinceconst data = {...}is not in the correct format for thedataargument tomapData. I think you wantmapData(data: { [key: string]: Array<number> }): void {...

There is no iteration in the code your provide. Is this what you want to achieve ?
for (key in data) {
mapData({key: key, value: data[key]}); }
