export class EntityVM implements EntityModel {

this.isCollapsed = isCollapsed;
}
}
public myFunction(myEntity: EntityVM) {
//!! here myEntity.isCollapsed is undefined instead of false
}
public myEntity = new Array<EntityModel>();
myFunction(myEntity)
When converting from EntityModel to EntityVM, the value for isCollapsed is not set to false.
It appears that there is an issue with your syntax in the code provided. The correct syntax should be as follows:
class EntityModel {}
export class EntityVM implements EntityModel {
public isCollapsed;
constructor(newEntity: EntityModel, isCollapsed = false) {
this.isCollapsed = isCollapsed;
}
}
const myEntity = new EntityVM({});
function myFunction(myEntity: EntityVM) {
console.log(myEntity);
}
myFunction(myEntity);
