get()
The get method returns the item at a given key or index. If the key or index does not exist, null is returned:
const collection = collect({
firstname: "Chuck",
lastname: "Norris"
});
collection.get("lastname");
//=> Norris
collection.get("middlename");
//=> null
const collection = collect(["a", "b", "c"]);
collection.get(1);
//=> b
You may optionally pass a default value as the second argument:
const collection = collect({
firstname: "Chuck",
lastname: "Norris"
});
collection.get("middlename", "default-value");
//=> default-value
You may even pass a callback as the default value. The result of the callback will be returned if the specified key does not exist:
const collection = collect({
firstname: "Chuck",
lastname: "Norris"
});
collection.get("middlename", () => "default-value");
//=> default-value
