What's the alternative for angular.isObject(value) in angular

Question

I'm migrating from AngularJS to Angular version 12 In AngularJS, I have the following operations:

angular.isObject(value) angular.isDefined(value) angular.forEach(value)

I want to know the alternatives in angular

Answer 1

Angular does not provide such methods. You can create your own replacements:

for angular.isObject you can do:

isObject(obj) {
   typeof obj === 'object' && obj !== null. 
}

for angular.forEach you have Object.entries which returns an iterable.

angular.isDefined is just

isDefined(obj) {
   typeof obj !== null && obj !== undefined. 
}
