Unary Operator: A unary operation contain only one operand. Here, the ‘+’ unary plus operator converts its operand to Number type. While it also acts as an arithmetic operator with two operands which returns an addition result on calculation....
JavaScript Relational Operators are used to compare their operands and determine the relationship between them. They return a Boolean value (true or false) based on the comparison result....
JavaScript in operator is used to check whether the data is within the object or in an array. In an object, the in operator works only on the key or property of the object. If the key or property exists then this operator returns true otherwise false. Similarly, for arrays, it will return true if we pass the index of the element not for a particular value....
The Unary plus(+) operation is a single operand operator (which means it worked with only a single operand preceding or succeeding to it), which is used to convert its operand to a number, if it isn’t already a number....
This operator is represented by x ||= y and it is called a logical OR assignment operator. If the value of x is falsy then the value of y will be assigned to x....
The Bitwise AND Assignment Operator is represented by “&=”. This operator uses the binary representation of both operands and performs the bitwise AND operation and then assigns the result to the left operand....
The Comparison Operator == (Equality operator) and === (Identity Operator) are used to compare two values. They are also known as the loosely equal (==) operator and the strict identical (===) operator....
PHP 7 introduced a null-coalescing operator with ?? syntax. This operator returns its first operand if its value has been set and it is not NULL, otherwise it will return its second operand. This operator can be used in a scenario where the programmer wants to get some input from the user and if the user has skipped the input, some default value has to be assigned to the variable....
This article will show you how to perform arithmetic operations in PHP. The arithmetic operators are used to perform simple mathematical operations like addition, subtraction, multiplication, etc....
JavaScript remainder assignment operator (%=) assigns the remainder to the variable after dividing a variable by the value of the right operand....
The Unary negation(-) operation is a single operand operator (which means it worked with only a single operand preceding or succeeding to it), which is used to convert its operand to a negative number, if it isn’t already a negative number....
