Contrast identical items within an angular framework

I am trying to compare two objects, but for some reason it is not working as expected.

Here is the code snippet I am using:

export class SourceValues {
  ...
  static INDICATOR: ISourceValue = { text: 'Indicator', value: 'Indicator' };
  ...
}

Elsewhere in the code:

let a = { text: 'Indicator', value: 'Indicator' } as ISourceValue;
...
if(a === SourceValues.INDICATOR){ // No changes should be needed here
//do something
}

When this code is executed, both a and SourceValues.INDICATOR seem to hold the same value/object, yet the comparison does not work as expected. Any insights on why this might be happening would be greatly appreciated. Thank you.

Answer №1

When working with objects in JavaScript, remember that you can't use the === operator to compare them. The reason is that === compares memory locations of objects, and since each object has its own unique memory location, the comparison will always result in false.

Answer №2

Unlike primitive types, objects in JavaScript are compared based on their references and will not be considered equal even if they have the same properties. For more information on object equality in JavaScript, check out this link:
