Here are a few important points to consider:
(1) It is recommended to avoid using Object as a type in TypeScript, as highlighted in the documentation:
The any type allows you to work with JavaScript seamlessly, enabling gradual opt-in and opt-out of type-checking during compilation.
Using Object may not provide the same flexibility as in other languages. Variables of type Object limit method invocation possibilities even if said methods exist.
Therefore, it's better to utilize any for more versatility:
export class MyClass {
name: any;
}
However, by using any or Object, you sacrifice the type safety features TypeScript offers. Instead, consider the following approach:
export class MyClass {
name: { [language: string]: string };
}
(2) The code snippet below poses an issue as it doesn't instantiate a new instance of MyClass; it merely creates an object with similar properties. This appears error-free due to TypeScript's structural subtyping nature.
To create an actual instance, try utilizing:
item = Object.assign(new MyClass(), {
name: { en: string }
});
Alternatively, establish a constructor that initializes data:
export class MyClass {
name: { [language: string]: string };
constructor(name: { [language: string]: string }) {
this.name = name;
}
}
item = new MyClass({
name: { en: string }
});
