Operators in Java Script

 

In JavaScript, operators are special symbols used to perform operations on values and variables. The values being acted upon are called operands.

For example, in 10 + 5, the + is the operator and 10 and 5 are the operands.
 
 
Types of Operators in Java Script: 
 
1. Arithmetic Operators
Used to perform standard mathematical calculations.
  • + (Addition): 5 + 2 // 7
  • - (Subtraction): 5 - 2 // 3
  • * (Multiplication): 5 * 2 // 10
  • / (Division): 10 / 2 // 5
  • % (Modulus/Remainder): 10 % 3 // 1
  • ** (Exponentiation): 2 ** 3 // 8
 
2. Assignment Operators
Used to assign values to variables.
  • = : Simple assignment (x = 10)
  • += : Addition assignment (x += 5 is the same as x = x + 5)
  • -=, *=, /= : Perform the math and assign the result.
 
3. Comparison Operators
Used to compare two values and return a Boolean (true or false).
  • == : Equal to (checks value only).
  • === : Strict equal (checks both value and data type—highly recommended).
  • != : Not equal to.
  • > / < : Greater than / Less than.
  • >= / <= : Greater than or equal / Less than or equal.
 
4. Logical Operators
Used to determine logic between variables or values.
  • && (Logical AND): Returns true if both statements are true.
  • || (Logical OR): Returns true if at least one statement is true.
  • ! (Logical NOT): Reverses the result (true becomes false).

 

5. The Ternary Operator
A shorthand for an if-else statement.
  • Syntax: condition ? valueIfTrue : valueIfFalse
  • Example: let status = (age >= 18) ? "Adult" : "Minor";
