Union Types in TS

Welcome to a youtube channel dedicated to programming and coding related tutorials. We talk about tech, write code, discuss about cloud and devops. That’s what we do all day, all year. We roll out a lot of series and videos on our channel.

All the learning resources such as code files, documentations, articles and community discussions are available on our website:

You can find our discord link, github link etc on the above website.

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;

Another great explanation almost impossible to find somewhere else

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?

[ankushthakur]

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

[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 ?

[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?
