System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

function getMinDeletions(s) {
  const ordered_string = s.split('').sort().join('');
  let delCount = 0;

  for (let i = 0; i < ordered_string.length; i++) {
      if (ordered_string[i] === ordered_string[i + 1]) {
          delCount++;
      }
  }

import { Directive, ElementRef, OnDestroy } from '@angular/core';
import * as textMask from 'vanilla-text-mask/dist/vanillaTextMask.js';

@Directive({
  selector: '[appMaskDate]'
})
export class MaskDateDirective implements OnDestroy {

  public mask = [/\d/, /\d/, '/', /\d/, /\d/, '/', /\d/, /\d/, /\d/, /\d/]; // dd/mm/yyyy
  public maskedInputController;
