Union Types in TS

[@HiteshCodeLab]

Are you aware of new batch of full stack javascript bootcamp ? hc.lco.dev/jscamp2

[@tushar207]

I have been an angular developer and worked with TS from the past 5 years, still there were a few things to take away from this video. Great work Hitesh

[@AashishKumar-vb3qb]

No one can explain union working with other data objects as perfectly as Hitesh explains in this video.

your TS videos make me powerful day by day☺

[@nobody20022]

Summary: Union type allows a variable to hold one of several specified types. It’s denoted by using the vertical bar (' | ') between types. This is useful when you want to allow multiple types for a single value, while still maintaining some level of type safety. Syntax: let value: string | number;

You are doing great Job but please please please complete this Typescript series and provide us all the topics available in Typescript, please do not stop this Typescript series after some videos 🙏🙏

[@HiteshCodeLab]

Don’t worry, this is not my 1st public playlist. JS is done, golang is done, TS will be done too 😁

[@mohitjain4453]

Thanks Hitesh 🙂 I have purchased your Angular course and Vue JS course from LCO and also going to purchase React JS course, I love your teaching style ❤️

[@sagar-tt4ub]

I'm like the video before watching because i know that its good video and helpful

[@tamoghnadey]

what if we do this - function getDBId(id: number | string) { // console.log(`db id is ${id}`); if (typeof id === "string") { id.toLowerCase(); } else { id = id.toString(); id += 1; } } when we are converting id to string in the else block it still allows us to add 1 to it in the next loc ideally we should not be able to do that, we can't add number to a string How can we avoid that? Or is it a flaw ?

[@vivekjaiswal2422]

There are two types of data types we can mention for any variable, either lowercase (number) or uppercase(Number). Mostly we will use lower case one, So why can't we go for upper case?

[@LaveshGarg]

Thank you sir for providing such a quality content

[@HiteshCodeLab]

You are welcome

[@ankushthakur2177]

Sir in the last.. I guess we can use Enum Type for strict checking

[@mdmostafizurrahman9275]

if i have to check using condition then what the need of TS ? if (typeof id === "number") { return id + 10; } else if (typeof id === "string") { return id.toUpperCase(); }

[@ZizouZ5]

there's no need for else or else if check here because ts is smart enough to infer the only remaining type 'string' for the id variable

Watching it in June 2024 ❤🔥

[@Userkazt]

type User= { username:string; role:string; } type Admin = { role:string; sudo:boolean; } let uncleBob : User | Admin = { username: 'uncle',role:'user',sudo:false} console.log(uncleBob) In this case, instead of User or Admin, it has combined both types of data into one. Is this a problem?

[@YouAndImpact]

Great 👍
