Tricky JavaScript Interview Question Using Array And Object Destructuring Combined |
https://dev.to/myogeshchavan97/tricky-javascript-interview-question-using-array-and-object-destructuring-combined-nj5
|
Tricky JavaScript Interview Question Using Array And Object Destructuring CombinedThe question goes like this Explain to me what the below line of JavaScript code does const isoCode firstCode allStates If you re new to array and object destructuring then this question might sound complicated But it s actually not So to be able to answer this question you first need to know some basics of array and object destructuring So let s revise that If you have an array like this const numbers Then to access values and we can use array destructuring like this const a b numbers console log a console log b If we want to access only the first element from the array we do it like this const a numbers console log a Now If we have an object like this const user name Mike age Then to access the name and age we can use object destructuring like this const name age user console log name Mikeconsole log age So now If we have an array of objects like this const allStates isoCode IN name India isoCode CA name Canada then we can access the first element of the array using array destructuring like this const firstObject allStates console log firstObject isoCode IN name India And If we want to access the isoCode property from the first object of the array we can use object destructuring inside array destructuring like this const isoCode allStates console log isoCode INBut If the isoCode property itself does not exist in the first object of the array then we will get undefined as the result The property might not exist because the allStates array data might come from API which might not have the isoCode property So to avoid getting undefined we can assign a default value while destructuring itself like this const isoCode allStates console log isoCode INHowever as the isoCode property already exists in our case we get isoCode as IN But If we have an array like this const allStates name India name Canada Then the value of isoCode will be an empty string like this const isoCode allStates console log isoCode But what If the allStates array itself is empty and it does not contain any object like this const allStates Then the below code will throw an error const isoCode allStates console log isoCode Cannot read properties of undefined reading isoCode We re getting an error because we re destructuring the isoCode property from the first element of the array but the first element itself does not exist So to avoid getting that error we can assign an empty object during object destructuring itself like this const isoCode allStates console log isoCode Here we get empty string as the isoCode value because destructuring an empty object will return undefined like this const obj const name obj console log name undefinedAnd as we re also using default value of an empty string If the property is undefined we will get empty string as the result for the above isoCode Also If we don t want to use the isoCode property name we can use renaming syntax during object destructuring like this const allStates isoCode IN name India isoCode CA name Canada const isoCode firstCode allStates console log firstCode INSo now you have all the knowledge to answer the initial question asked Explain to me what the below line of JavaScript code does const isoCode firstCode allStates Answer In the above code we re using array destructuring syntax to destructure the first element of the allStates array And from the first element of the array which is an object we re destructuring the isoCode property to find out its value If the isoCode property itself does not exist then we re assigning an empty string to be its value And If the allStates array comes as empty then to avoid getting a JavaScript error we re also assigning an empty object during object destructuring And finally we re using renaming syntax to rename the isoCode property to firstCode So If we have an array like this const allStates isoCode IN name India isoCode CA name Canada Then we will get IN as the result as shown below const isoCode firstCode allStates console log firstCode IN And If we have an array like this const allStates name India name Canada Then we will get an empty string as the result as shown below const isoCode firstCode allStates console log firstCode And If we have an array like this const allStates Then we will again get an empty string as the result as shown below const isoCode firstCode allStates console log firstCode But we will never get an error If the allStates is an empty array Closing pointsKnowing destructuring is very important as a JavaScript React developer as it greatly simplifies your code If you want to learn all ES features in depth in an easy to understand way do check out my Mastering Modern JavaScript book You can also check out the free preview of the book content in this freeCodeCamp article In this ebook you will also learn all the prerequisites you should know before starting to learn React js Want to stay up to date with regular
