  • angular.isArray() : Check object is Array or not , Returns true if the object is an Array.
  • angular.isDate() : Check object is Date or not , Returns true if the object is an Date.
  • angular.isDefined() :Check object is defined or not , Returns true if the object is an defined.
  • angular.isElement() :Check object is element or not , Returns true if the element is an defined.
  • angular.isFunction() : Check object is function or not , Returns true if the function is an defined.
  • angular.isNumber() : Check object is number or not , Returns true if the object is an number .
  • angular.isObject()  : Check object  or not , Returns true if the object .
  • angular.isString()  : Check object is string or not , Returns true if the string is an number .
  • angular.isUndefined() : Check object is defined or not , Returns true if the defined .
  • angular.equals() : Returns true if two object are equal.
Below are some of the compare example from the above list.
