Operators in M7 Script

Overview

Operators in M7 Script are symbols that perform operations on variables and values. They are categorized based on their functionality.

1. Arithmetic Operators

Used for mathematical operations:

var sum = a + b;   // Addition
var diff = a - b;  // Subtraction
var prod = a * b;  // Multiplication
var div = a / b;   // Division
var mod = a % b;   // Modulus (remainder)

2. Comparison Operators

Used to compare values and return a Boolean result:

var isEqual = a == b;   // Equal to
var isNotEqual = a != b; // Not equal to
var isGreater = a > b;   // Greater than
var isLesser = a < b;    // Less than
var isGreaterOrEqual = a >= b; // Greater than or equal to
var isLesserOrEqual = a <= b;  // Less than or equal to

3. Logical Operators

Used for Boolean logic:

var andResult = a && b;  // Logical AND
var orResult = a || b;   // Logical OR
var notResult = !a;      // Logical NOT

4. Bitwise Operators

Used for bit-level operations:

var bitAnd = a & b;  // Bitwise AND
var bitOr = a | b;   // Bitwise OR
var bitXor = a ^ b;  // Bitwise XOR
var leftShift = a << b; // Left Shift
var rightShift = a >> b; // Right Shift

5. Assignment Operators

Used for assigning values to variables:

a = b;   // Assign
a += b;  // Add and assign
a -= b;  // Subtract and assign
a *= b;  // Multiply and assign
a /= b;  // Divide and assign
a %= b;  // Modulus and assign
a &= b;  // Bitwise AND and assign
a |= b;  // Bitwise OR and assign
a ^= b;  // Bitwise XOR and assign
a <<= b; // Left shift and assign
a >>= b; // Right shift and assign

6. Unary Operators

Operate on a single operand:

var neg = -a;  // Negation
var pos = +a;  // Explicit positive
var increment = ++a; // Pre-increment
a++; // Post-increment
var decrement = --a; // Pre-decrement
a--; // Post-decrement
var bitNot = ~a; // Bitwise NOT

7. Ternary Operator

A shorthand for conditional expressions:

var result = (a > b) ? "A is greater" : "B is greater";

8. Concatenation Operator

Used to join strings:

var fullName = firstName . " " . lastName;

9. Spread Operator

Used to unpack values from arrays or pass multiple arguments:

function sum(...numbers) {
    var total = 0;
    for (num in numbers) {
        total += num;
    }
    return total;
}
