[Sept Sprint] Cars Assemble

[iHiD]

This is part of our September Spring to get the Go Track in shape. Please read the Overview issue for more details. This exercise is claimed by @jmrunkle.

Cars Assemble

• Add arithmetic-operators as a concept
  • Intro should have a table with the standard operators +,-,*,/,%,
  • Intro should explain what happens for integer division (e.g. 5 / 2 = 2)
  • Intro should introduce shorthand assignments += etc.
  • Add arithmetic-operators to the concepts property of cars-assembly entry in the config.json file
  • Add an entry to the concepts array for the arithmetic-operators concept
  • Create a concepts/arithmetic-operators directory with its required files
• Add comparison as a concept
  • Add the comparison concept to the cars assemble exercise's concepts array in the config.json
  • Add an entry for the comparison concept to the concepts array in the config.json
  • Create a concepts/comparison directory with its required files (check this JS example for inspiration)
• cars-assemble is supposed to teach conditionals-if but the stub already implements the only method that uses conditionals #1542
• cars-assemble: update type conversion introduction #1576
• cars-assemble: remove links from introduction #1575
• cars-assemble: explain if expression; condition { } syntax #1644
• cars-assemble: remove type-conversion concept #1675
• cars-assemble: add implementation of successRate() as a task #1710

Claiming this one since it looks like low-hanging fruit.

Great. There's a question about whether this should also teach comparison. @junedev/@ErikSchierboom are discussing and will follow up on that on Tues :)

@jmrunkle #1675 Has been added to the list of tasks.

Since the comparison concept was previously planned to one of the exercises I was looking into, I already started making it and can take care of that task.

[ErikSchierboom]

Perfect!

[jmrunkle]

Since the comparison concept was previously planned to one of the exercises I was looking into, I already started making it and can take care of that task.

It looks to me like that should not be part of this issue's set of tasks anymore since it is about the blackjack exercise. Am I mistaken?

[junedev]

@jmrunkle That was a copy and paste error from Erik. I fixed it.

The comparison concept introduces >, ==, etc which needed in this exercise. That is why introducing it in black jack would be "too late" in the concept tree so Erik indeed meant for it to be added to cars assemble.

Note that to avoid overloading the introduction, we are cutting down the type conversion part in return, see #1675.
