• Logical operators, && and ||
• Loops, loop and break
• Mutate variables:

let foo = 1;
foo = foo + 1;
foo; //2

• Postfix operators on variables, foo++; and bar--;

Instructions

Build the app:

cargo build --release

To start the repl using the compiler/vm:

./target/release/repl

To start the repl using the interpreter:

./target/release/repl --mode eval

To execute a .monkey file with the compiler/vm:

./target/release/repl monkey_examples/fibonacci.monkey

To execute a .monkey file with the interpreter:

./target/release/repl monkey_examples/fibonacci.monkey --mode eval

Benchmark between compiler and interpreter:

Computing the 25^th fibonacci integer.
