Linting (ESLint) and Formatting (Prettier) in Angular

Term	Tool	Explanation	Use	Docs
🔦 Linter	ESLint	- Runs a set of discrete rules - Slower - Explicit logic for edge cases	Code quality (bug catching)	📑
🧹 Formatter	Prettier	- Reformats in one pass - Faster - Can't find and fix bugs	Code Formatting	📑

• eslintconfigprettier -> Prettier -> Lint

Linters have two categories of rules:

import 'dart:collection';
import 'dart:math';

class IndexableSkipList<K, V> {
  static const _maxHeight = 12;

  final _Node<K, V> _head = _Node(
    null,
    null,
    List.filled(_maxHeight, null),

// Add the values you want
rsi = ta.rsi(close,14)

// Define the function
// With one call, you'll get back 9 values
fGetImported(_timeframe) =>
    request.security(symbol = syminfo.tickerid, timeframe = _timeframe, expression = [open, high, low, close, rsi, open[1], high[1], low[1], close[1]], gaps = barmerge.gaps_off)

// Implement the function for different timeframes
// 3 timeframes

//To create a new controller, you only need to copy this code and change 2 items:
//1. dbTitle = new collection name
//2. dbFieldsArray = fields in the new collection
