The “==” operator is often used to compare two values, such as checking if a variable is equal to a certain value or comparing two strings to see if they are the same. It can also be used to compare objects, arrays, and other data types. It is important to note that the “==” operator does not check if two objects are the same object, it only checks if they have the same value.
In addition to the “==” and “===” operators, there are also the “!=” and “!==” operators. These operators are the opposite of the “==” and “===” operators, meaning they will return true if two values are not equal or not of the same type. It is important to note that the “!=” operator does not check for type equality, so it will return true if two values are not equal in value but are of the same type.
