The nullish coalescing operator (??) is a logical operator that takes two arguments. It returns the right-hand side operand when its left-hand side operand is null or undefined. otherwise, it returns its left-hand side operand.
An assignment operator requires two operands. The value of the right operand is assigned to the left operand. The sign = denotes the simple assignment operator. JavaScript also has several compound assignment operators, which is actually shorthand for other operators. A list of all such operators are listed below.
several operators available Bitwise AND (&), Bitwise OR (|), Bitwise XOR (^), Bitwise NOT (~), Left Shift (<<), Sign-propagating right shift (>>) and Zero-fill right shift (>>>).
The Logical operators operate on a set of operands and return one of the operands as a return value. It is typically used on boolean operands, in which case the return value is a boolean. If the operands and not boolean values, then logical operators may return a non-boolean value. JavaScript has four logical operators. They are AND (&& ), OR ( || ) , NOT (!) & Nullish coalescing operator (??).
The JavaScript conditional operator is a Ternary Operator, which takes three operands. The first operand is condition to evaluate. It is followed by a question mark (?), then an expression (expression1). It is then followed by a colon (:) and second expression (expression2). If the condition is true, then expression1 executes & if the condition is false, then expression2 executes. The conditional operator is a shorthand way to write an if-else statement.
