    Operators

    There are several special operators that do not fit into any other category:
    Arithmetic Operators

    (+, -, *, /, %, ++, --, unary -, unary +)

    Arithmetic operators take numerical values (either literals or variables) as their operands and return a single numerical value.

    Assignment Operators

    (=, *=, /=, %=, +=, -=, <<=, >>=, >>>=, &=, ^=, |=)

    An assignment operator assigns a value to its left operand based on the value of its right operand.

    Bitwise Operators

    (&, |, ^, ~, <<, >>, >>>)

    Bitwise operators treat their operands as a set of 32 bits (zeros and ones) and return standard JavaScript numerical values.

    Comparison Operators

    (==, !=, ===, !==, >, >=, <, <=)

    A comparison operator compares its operands and returns a logical value based on whether the comparison is true.

    Logical Operators

    (&&, ||, !)

    Logical operators are typically used with boolean (logical) values, and when they are, they return a boolean value.

    String Operators

    (+ and +=)

    The string operators concatenate two string values together, returning another string that is the union of the two strings.

    Member Operators

    (object.property and object["property"])

    Member operators provide access to a property or method of an object.

    Special Operators
    Conditional Operator

    (condition ? ifTrue : ifFalse)

    The conditional operator returns one of two values based on the logical value of the condition.

    Comma Operator

    (,)

    The comma operator allows multiple expressions to be evaluated in a single statement and returns the result of the last expression.

    delete Operator

    (delete)

    The delete operator deletes objects.

    function Operator

    (function)

    The function operator defines a function.

    get Operator

    (get)

    The get operator defines a property to be a getter.

    in Operator

    (in)

    The in operator determines whether an object has a given property.

    instanceof Operator

    (instanceof)

    The instanceof operator determines whether an object is an instance of another object.

    let Operator

    (let)

    The let operator temporarily assigns a value to a variable that only effects an expression.

    new Operator

    (new)

    The new operator creates an instance of a constructor.

    set Operator

    (set)

    The set operator defines a property to be a setter.

    this Operator

    (this)

    The this operator refers to the execution context.

    typeof Operator

    (typeof)

    The typeof operator determines the type of a given object.

    void Operator

    (void)

    The void operator discards an expressions return value.

    yield Operator

    (yield)

    The yield operator determines what is returned in a generator by that generator's iterator.

    Operator Precedence
    Operator precedence defines the order in which operators are evaluated.
