Operators JS

Arithmetic operators

These operators are used to do mathematical calculations:

Addition operator (+)

  let x = 4;
  let y = 5;

  console.log(x + y);

Subtraction operator (-)

  let x = 4;
  let y = 5;

  console.log(x - y);

Multiplication operator (*)

  let x = 4;
  let y = 5;

  console.log(x * y);

Division operator (/)

  let x = 4;
  let y = 5;

  console.log(x / y);

Modulus operator (%)

  let x = 4;
  let y = 5;

  console.log(x % y);

Exponentiation operator (**)

  let x = 4;
  let y = 5;

  console.log(x ** y);

Assignment operators

These operators are used to assign values to variables. They include:

Assignment operator (=)
```
  let x = 5;
```
Addition assignment operator (+=)
```
  let x = 4;
  x += 5;  // x = x + 5
```
Subtraction assignment operator (-=)
```
  let x = 14;
  x -= 5; // x = x - 5
```
Multiplication assignment operator (*=)
```
  let x = 14;
  x *= 5;  // x = x * 5
```
Division assignment operator (/=)
```
  let x = 15;
  x /= 5;  // x = x / 5
```
Modulus assignment operator (%=)
```
  let x = 15;
  x %= 5;  // x = x % 5
```

Comparison operators

These operators are used to compare values. They include:

Equal to operator (==)

  5 == 5 // true
  5 == '5' // true
  'hello' == 'Hello' // false
  // This operator compares two values for equality, and returns true if they are equal, and false otherwise.

Not equal to operator (!=)

  5 != 3 // true
  5 != 5 // false
  'hello' != 'Hello' // true
  // returns true if they are not equal, and false otherwise

Strict equal to operator (===)

  5 === 5 // true
  5 === '5' // false
  // This operator compares two values for strict equality and returns true if they are both of the same type and have the same value, and false otherwise.

Strict not equal to operator (!==)

  5 !== 3 // true
  5 !== 5 // false
  'hello' !== 'Hello' // true
  // returns true if they are either not of the same type or not the same value, and false otherwise.

Greater than operator (>)
```
  5 > 3 // true
  5 > 10 // false
```
Less than operator (<)
```
  5 < 10 // true
  5 < 3 // false
```
Greater than or equal to operator (>=)
```
  5 >= 5 // true
  5 >= 10 // false
```
Less than or equal to operator (<=)
```
  5 <= 10 // true
  5 <= 3 // false
```

Logical operators

These operators are used to combine or negate boolean values. They include:

Logical AND operator (&&)

  let x = 5;
  let y = 10;
  if (x > 0 && y > 0) {
    console.log("Both x and y are positive.");
  }
  // Output: "Both x and y are positive."

Logical OR operator (||)

  let x = 5;
  let y = 10;
  if (x > 0 || y > 0) {
    console.log("At least one of x and y is positive.");
  }
  // Output: "At least one of x and y is positive."

Logical NOT operator (!)

  let x = 5;
  let y = 10;
  if (!(x > y)) {
    console.log("x is not greater than y.");
  }
  // Output: "x is not greater than y."
