Well, if equality by value was important to you and you wanted to useFooin aHashSet<Foo>, you could end up adding twoFooinstances with identical values to yourHashSet<Foo>by accident - because that collection keys off of the hashcode of eachFooobject to determine uniqueness. There are lot...
For more information about string comparison, see How to compare strings in C#. Delegate equality Two delegate operands of the same run-time type are equal when both of them are null or their invocation lists are of the same length and have equal entries in each position: C# Copy Run ...
The exception is for strings; comparing strings with == does make things much simpler and more readable but you need to remember that both sides of the operator must be expressions of type string for the comparison to work properly. C# Equality Operator Equals method in C# operator operat...

for any numberx. Thus equality is not reflexive in JavaScript, becauseNaNis not equal to itself. Two booleans, two strings (primitive): obvious results Two objects (including arrays and functions):x === yonly ifxand y are the same object(!). That is, if you want to compare different ...
you implement value equality when you expect to add objects of the type to a collection, or when their primary purpose is to store a set of fields or properties. You can base your definition of value equality on a comparison of all the fields and properties in the type, or you can base...
of equality. When programming in Java, a common pitfall for beginners is to compare objects with==when they should have been compared withequals. For instance, comparing two stringsxandyusing "x==y" might well yieldfalsein Java, even ifxandyhave exactly the same characters in the same order...
same assembly are always interned by the runtime. That is, only one instance of each unique literal string is maintained. However, the runtime does not guarantee that strings created at runtime are interned, nor does it guarantee that two equal constant strings in different assemblies are ...

Their values. The "value" of an object is Clojure’s equality main ingredient. One consequence is that collections don’t necessarily need to have the same type to be equal. Values satisfy the common intuition that (1 2) and [1 2] are equal, despite the
