Recently, I've been utilizing a code snippet to verify the value of an input field located at index:1 within an array. The code looks like this:
const inputValue=journeyData && journeyData.birthdate && journeyData.birthdate[0]
? journeyData.birthdate[0]
: null,
I am now curious if there is a lodash alternative that can achieve the same outcome more succinctly?
Utilize the built-in optional chaining feature instead of relying on lodash.
const journeyData = { birthdate: [new Date()] };
const inputValue = journeyData?.birthdate?.[0] ?? null;
const inputValue2 = journeyData?.birthdate?.[2] ?? null;
console.log(inputValue);
console.log(inputValue2);For further reference, check out:
If you're looking to retrieve values from nested objects in JavaScript, one handy approach is using the _.get() function provided by Lodash library. It allows you to specify a path along with a fallback value in case the specified path doesn't exist:
function fetchValue(data) {
const result = _.get(data, "address.street[0]", null);
return result;
}
console.log( fetchValue() ); // null
console.log( fetchValue({}) ); // null
console.log( fetchValue({ address: {} }) ); // null
console.log( fetchValue({ address: { street: [123] } }) ); // 123<script src="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="5c3033383d2f341c68726d6b726e6d">[email protected]</a>/lodash.min.js"></script>Looking to create an Array of objects with enum properties. export enum MyEnum { FIXTERM1W = 'FIXTERM_1W', FIXTERM2W = 'FIXTERM_2W', FIXTERM1M = 'FIXTERM_1M', FIXTERM2M = 'FIXTERM_2M', FIXTERM3M = 'FIX ...
