typescript ?: code example

Example 1: use type as value typescript

Typescript interfaces aren''t being compiled into the js output, and you can not use them at runtime

Example 2: typescript

interface LabelledValue {
  label: string;
}

function printLabel(labelledObj: LabelledValue) {
  console.log(labelledObj.label);
}

let myObj = {size: 10, label: "Size 10 Object"};
printLabel(myObj);

Example 3: typescript

npm install -g typescript

Example 4: typescript

it's just js with types okay just switch it's not that hard

Great compiler for Javascript
