What are the operators in js
JavaScript operators are tools that perform various operations, including arithmetic operations (such as addition, multiplication), assignments (such as assigning values to variables), comparisons (such as checking equality), logical operations (such as AND or not), and bit operations (such as bitwise AND or XOR).
Operators in JavaScript
The JavaScript language provides a wealth of operators for performing various operate. These operators can be divided into the following categories:
1. Arithmetic operators
- Addition ( ): Add two or more numbers.
- Subtraction (-): Subtract one number from another number.
- Multiplication (*): Multiply two numbers.
- Division (/): Divide one number by another number.
- Modulo (%): Take the remainder of the division of two numbers.
- Increment ( ): Add 1 to a number.
- Decrease (--): Decrease a number by 1.
2. Assignment operator
- Single equal sign (=): Assign a value to a variable.
- Add equals (=): Add a value to a variable.
- Minus equals (-=): Subtract a value from a variable.
- Multiply equals (*=): Multiply a variable by a value.
- Division equals (/=): Divide a variable by a value.
3. Comparison operator
- Equal (==): Compares whether two values are equal.
- Strict equals (===): Compares whether two values are equal and of the same type.
- Not equal to (!=): Compares whether two values are not equal.
- Not strictly equal (!==): Compares whether two values are not equal or have different types.
- Greater than (>): Compares whether one value is greater than another value.
- Greater than or equal to (>=): Compares whether a value is greater than or equal to another value.
- Less than (<): Compares whether one value is less than another value.
- Less than or equal to (<=): Compares whether one value is less than or equal to another value.
4. Logical operators
- And (&&): Returns true only if both operands are true.
- Or (||): Return true as long as one operand is true.
- Not (!): Negate a value.
5. Bitwise operators
- Bitwise AND (&): performs an AND operation on each bit of two numbers.
- Bitwise OR (|): OR operation on each bit of two numbers.
- Bitwise XOR (^): Performs XOR operation on each bit of two numbers.
- Bitwise left shift (<<): Shift the bits of a number to the left by the specified amount.
- Bitwise right shift (>>): Move the bits of a number to the right by the specified amount.
6. Other operators
- Comma (,): used to separate two or more expressions.
- Question mark (?): used for ternary conditional operations.
- Colon (:): used for ternary conditional operations.

Core points This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called. When there is no current object, this refers to the global object. In a web browser, it is represented by window. When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object. You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
