Operators in JavaScript

In JavaScript, JavaScript is a full range of operators, including arithmetic, logic, bits, assignments, and some other operators.

strictly equal = = =

Non-Strictly equal!==

The difference between = = (equality) and = = = (strictly equal) is that the identity operator casts different types of values before comparison. For example, the identity pair string "1" and the value 1 will result in a comparison of true. Strict equality does not cast values of different types, so it considers the string "1" to be not the same as the value 1.

The basic string, numeric, and Boolean values are compared by value. If their values are the same, the comparison results are equal. objects, including array, Function, String, number, Boolean, Error, date, and RegExp objects, are compared by reference. Even if the two variables of these types have the same value, the result is true only if they are exactly the same object.

Two basic strings with the same value.

var string1 = "Hello";

var string2 = "Hello";

A two String object with the same value.

var StringObject1 = new String (string1); www.mlyrx120.com

var StringObject2 = new String (string2);

The comparison result is true.

if (string1 = = string2)

Executes some commands (which will run).

The comparison result is false.

if (StringObject1 = = StringObject2)

Execute some commands (not run).

To compare the value of a String object,

Use the toString () or ValueOf () method.

if (stringobject1.valueof () = = StringObject2)

Executes some commands (which will run).
