Operators

In programming, symbols such as plus (+), minus (-), multiply (×), and divide (÷) are called Operators.

Operators are used to process data (values) and create new values.

Frequently used operators include arithmetic operators, comparison operators, and logical operators.

These perform basic mathematical operations like elementary arithmetic.

• + : Addition

• - : Subtraction

• * : Multiplication

• / : Division

• % : Modulus

Copy
let result = 5 * 3; // 5 x 3 = 15 is stored in result

They compare values or variables and return a boolean value, either true or false.

• == : Equal to (compares only values)

• === : Strict equal to (compares values and types)

• != : Not equal

• !== : Strict not equal

• > : Greater than

• < : Less than

• >= : Greater than or equal to

• <= : Less than or equal to

Copy
let isTrue = 5 > 3; // 5 > 3 results in true being stored in isTrue

These are used to combine multiple conditions to determine a boolean value, true or false.

• && : AND - true only if both are true

• || : OR - true if at least one is true

• ! : NOT - inverts true to false and false to true

Copy
let value = true && false; // true && false results in false being stored in value
