# Note, the expressions for the first three tasks must end with commas.

|
|
# Recall that a jq program is a *single expression*. For this exercise,
|
|
# you are solving four separate tasks with one source file. Use the
|
|
# comma operator so the outputs of these filters are joined into a
|
|
# single output stream. jq prints each item in a data stream on a
|
|
# separate line, which makes the tests easier to write.
|
|
#
|
|
# This is an error:
|
|
# jq -n '
|
|
# 1
|
|
# 2
|
|
# 3
|
|
# '
|
|
#
|
|
# With commas, it is OK:
|
|
# jq -n '
|
|
# 1,
|
|
# 2,
|
|
# 3
|
|
# '
|
|

|
# You'll need to use parentheses to control order of operations

|
# Task 1: replace `null` with the "name" element of the shopping list.

# Task 2: replace `null` with the count of the required ingredients.

# Task 3: replace `null` with the amount of sugar.
