React.js Interview – technical submission and detailed feedback

@Negatives
- code look messy and unnecessarily made complicated
- created a common http get service around axois, the implementation is not proper
- unnecessary component wrappers, just for using some CSS classes
- usage of error boundary is not in the recommended way
- unnecessarily added new functionality rather than concentrating on the complete solution
- unnecessarily suppressing lint rules
- not handling mobile responsiveness

@Instruments page / stock listing
 - api call twice on page mount
 - using 2 different state for search results and default view
 - filter function will always runs

@Quotes page / stock detail page
 - api call twice on page mount
 - polling is implemented but the implementation is messy and won't work
 implementation details
      - spawn a web worker and listen for post message, inside this if the quotes list length is 0 make an api call to update the quotes
      - providing the user a control to update the interval (1,2,3,5,10 ms) for checking expired quotes
      - there's  a  set interval run on this interval (1..10 ms) inside this posting a web worker message
      - web worker will run the loop for checking the quote's expiry and the expired leg is removed from the list
      - once all items have been removed from the list, initiate the api call to fetch new quotes, this time frontend will hit the server at least 100-300 times (sometimes more than 1800 requests)       reasons for this the web worker will receive a message every 1-10ms and hit the server
 - not properly clearing set interval, leads to calling the previous apis as well, now the loop will hit the server more than 5k times
 - Use string split and replace T and Z to convert the timezone for comparing the time
 - timestamp not converted to IST in the table listing

@Positives
- Using typescript
- Using error boundaries
- segregating code by spliting components and util functions
Instruments page
- implemented search
Quotes page
- implemented sort
