Since Java lambdas are closures, they can "capture" the values of variables in the enclosing lexical scope. While not all lambdas capture anything -- simple lambdas like s -> s.length() capture nothing and are called stateless -- capturing lambdas require a temporary object to hold the...

index.js
\- node_modules
\- foo
|- foo.js
\- package.json

Individual elements can be accessed through indexes. Python arrays are zero-indexed. Here is an example :
my_array = array('i', [1,2,3,4,5])
print(my_array[1])
# 2
print(my_array[2])
# 3
print(my_array[0])
# 1
my_array = array('i', [1,2,3,4,5])
my_array.append(6)
# array('i', [1, 2, 3, 4, 5, 6])
Note that the value 6 was appended to the existing array values.
