![]() Let’s imagine a Box type that can contain any value - strings, numbers, Giraffes, whatever. To display a JSON object using ngFor in Typescript, you can use the keyvalue pipe. This method returns an array of a given object’s own enumerable properties. Here is an over-simplified solution in plain old JavaScript. The principal difference between the two is how conflicts are handled, and that difference is typically one of the main reasons why you’d pick one over the other between an interface and a type alias of an intersection type. What you want to do, is to store all those objects within an array. With interfaces, we could use an extends clause to extend from other types, and we were able to do something similar with intersections and name the result with a type alias. We just looked at two ways to combine types which are similar, but are actually subtly different. Did you mean to write 'radius'? Try Interfaces vs. Iterate or Loop through each Array item or Object using AngularJS forEach. This means that if you build a list of new objects from scratch with the exact same values as the previous list and pass this newly built list to ngFor, Angular will not be able to tell that a given list item is already present or not. Object literal may only specify known properties, but 'raidus' does not exist in type 'Colorful & Circle'. ngFor by default tracks list items using object identity. Now let’s create a header for our App named My Custom Table. angular create a pipe to get value for key in angular create map object and. Open the file and delete all the contents from it. div ngFor" let item of testObject keyvalue" >.

Creating Table in Angular Now, first, go to the src folder under which go to the app folder. This is how to set all local variables with ngFor: .Let mySquare = createSquare (' is not assignable to parameter of type 'Colorful & Circle'. For Angular Projects, I recommend Visual Code Editor and we can open our project by typing code.
