experiment-js-foreach

small experiment with javascript foreach routine in node. Shows what to expect when trying a forEach() on an array vs. an object read from a yaml file.

Usage

npm install

installs dependencies

node expariment.js

runs the expariment

Expected Output

The expariment reads the.yaml file, which has an object and an array. Both the object and the array are run through forEach() so the result can be observed. We should expect to see the following:

╰─➤  node expariment.js
the parsed object
{ top: { obj: { foo: 'bar', baz: 'quux' }, arr: [ 'bar', 'quux' ] } }
[ 'bar', 'quux' ]
{ foo: 'bar', baz: 'quux' }
foreach() on array type
bar
quux
foreach() on object type
=== error in foreach() object
TypeError: ob.forEach is not a function

    at tryToString (fs.js:457:3)
    at FSReqWrap.readFileAfterClose [as oncomplete] (fs.js:444:12)

which shows how the object is read and encoded, then the successful foreach on an array, followed by the error found when running forEach on the object type.
