[sicpjs/1.1.6] Incorrect Solutions to Exercise 1.1 (`const` examples)

[jdfm]

Both when running the example code in the inline IDE and also in the browser's console, the following expressions result in undefined being printed:

// exercise 1.1.6
const a = 3; // prints undefined

// exercise 1.1.7
const b = a + 1; // prints undefined

In the solutions, the values listed are 3 and 4 respectively. Which, given the results above, is incorrect.

The expressions that do result in 3 and 4 would be:

a = 3; // prints 3
b = a + 1; // prints 4

See attached screenshots for proof.

Yes, the solution should indicate that these two cases

// exercise 1.1.6
const a = 3; // prints undefined

// exercise 1.1.7
const b = a + 1; // prints undefined

should print undefined. Constant declarations don't produce any value in JavaScript. Chapter 1 doesn't mention this, but the excercise solution would be an opportunity to point this out.
