Typescript : strictPropertyInitialization flag in tsconfig

 In tsconfig.json there is flag strictPropertyInitialization

Here is example code

class UserAccount {

name: string;

accountType = "user";

email: string;

address: string | undefined;

constructor(name: string) {

this.name = name;

// Note that this.email is not set

}

}

In this class in constructor we are not initializing variable email which is not initilized at time of declaration also.

This will give error.

To Fix it

class UserAccount {

name: string;

accountType = "user";

email: string;

address: string | undefined;

constructor(name: string,email:string) {

this.name = name;

this.email = email

}

}
