Each block has a list of its statements.
```
printNode(cfg.blocks[0].statements[0])
console.log(printNode(cfg.blocks[0].statements[0])); // printNode returns a string
```
prints `x, y = 0, 0`.

The methods `cfg.getSuccessors` and `cfg.getPredecessors` allow the edges to be followed forward or backward.
```
const cond = cfg.getSuccessors(cfg.entry)[0];
printNode(cond)
console.log(printNode(cond.statements[0]));
```
prints `x < 10`.
