Aggregate by Operation
This is a further development of Convert and Aggregate mission. You are given an Array of tuples. Each tuple consists of two values: a string and a number. You need to create and return an Object, where keys are string values (except the first character) from input tuples. Values are aggregated number values from input tuples for each specific key. Each aggregating operation must be done according to the operation sign - the first character of string key. Division by zero should be ignored. The resulted Object should not include items with empty key or zero value.
Input: Array of tuples.
Output: Object.
Examples:
assert.deepStrictEqual(
aggrOperation([
["+a", 7],
["-b", 8],
["*a", 10],
]),
{ a: 70, b: -8 }
);
assert.deepStrictEqual(aggrOperation([]),...
CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.
In order to install CheckiO client you'll need installed Python (version at least 3.8)
Install CheckiO Client first:
pip3 install checkio_client
Configure your tool
checkio --domain=js config --key=
Sync solutions into your local folder
checkio sync
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium
Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
