An "assertion" is a statement or declaration that something is true or factual, often presented as a claim without providing evidence or proof at that moment. In various contexts, assertions can refer to:
- General Use: A confident and forceful statement of fact or belief.
- Logical and Philosophical Contexts: A proposition or statement that can be evaluated for its truth value.
- Programming: A statement in code that checks if a condition is true at a specific point in the program; if it is false, the program may produce an error or stop execution.
In summary, an assertion is essentially a way of stating something confidently, with the implication that it is accepted as true.
