Conditions

This module provides a collection of utility functions for working with conditional logic and boolean operations.

Value Checking

Checks if a value is defined (not null and not undefined).

typescript
isDefined(5) // returns true
isDefined(null) // returns false
isDefined(undefined) // returns false

Checks if a value is not defined (null or undefined).

typescript
isNotDefined(null) // returns true
isNotDefined(5) // returns false

Checks if a value is truthy.

typescript
isTruthy(true) // returns true
isTruthy(1) // returns true
isTruthy("") // returns false

Checks if a value is falsy.

typescript
isFalsy(false) // returns true
isFalsy(0) // returns true
isFalsy("hello") // returns false

Compares two values for strict equality.

typescript
isEqual(5, 5) // returns true
isEqual(5, "5") // returns false

Compares two values for inequality.

typescript
isNotEqual(5, "5") // returns true
isNotEqual(5, 5) // returns false

Negates a boolean value.

typescript
negate(true) // returns false
negate(false) // returns true

Performs a logical OR operation.

typescript
or(true, false) // returns true
or(false, false) // returns false

Performs a logical AND operation.

typescript
and(true, true) // returns true
and(true, false) // returns false

Returns one of two values based on a condition.

typescript
conditionalReturn(true, "yes", "no") // returns "yes"
conditionalReturn(false, "yes", "no") // returns "no"
