In computer science, logic, and mathematics, true and false are the two fundamental Boolean values used to represent binary logic and truth conditions. They dictate how conditional paths execute and form the logical foundation of all modern software engineering. Core Mechanics
Boolean Logic: Named after George Boole, this system reduces logic to binary values: true (1) and false (0).
Conditional Control: Programming languages use true and false inside if/else statements to decide which code block to execute.
Comparison Operators: Expressions like 5 > 3 evaluate to true, while 2 == 4 evaluates to false. Representation Across Languages Language / Context True Representation False Representation Python True False Capitalized; evaluates as integers 1 and 0 under the hood. JavaScript / Java / C++ true false Lowercase keywords built directly into the language syntax. C (Standard) Non-zero integer (usually 1) 0
Traditional C lacks a native boolean type without 1 / High Voltage 0 / Low Voltage The physical reality of transistors switching states. The Concept of “Truthy” and “Falsy”
Many dynamic programming languages evaluate non-boolean data types as either true or false when placed in a logical context (like an if statement condition).
Falsy Values: Items that resolve to false. Common examples include 0, empty strings ””, null, undefined, NaN, and empty structures like [] or {} (depending on the language).
Truthy Values: Virtually everything else. Any non-zero number, filled string, or valid object reference evaluates to true. Logical Operators
Boolean values are combined and manipulated using three primary logical gates: AND (&& or and): Returns true only if both inputs are true. OR (|| or or): Returns true if at least one input is true.
NOT (! or not): Inverts the value (true becomes false and vice versa).
