Sentient is declarative
Sentient is a declarative programming language, similar to Prolog, miniKanren and Alloy. Programs are descriptions of problems, rather than precise sets of instructions for the computer to follow. Sentient changes how you think about programming.
For example, an imperative program that solves Sudoku puzzles might try putting random numbers in the grid, then backtracking if it turns out they were incorrect. A declarative program would describe the rules of the puzzle, but wouldn’t implement an algorithm to solve it. The language implementation is responsible for that.
Another way to think about this is to assume someone has given you a solution to your problem. A Sentient program describes how to check that solution for correctness. Sentient uses this description and works backwards to solve the problem for itself.
