[solved] how to avoid minor errors in the coding process as effectively as possible

here"s the thing

in order to learn koa + mongoose , I get up at 5:30 every morning and start working. As a result, I ran into a bug that can"t be bypassed the other day. It was excruciating. The first thing I did when I opened my eyes was to deal with this problem. I was reluctant to get off the plane at work for two consecutive mornings, and I was almost late.
the result is just now, just now.. It was found that a pair of [] square brackets were left out. I just couldn"t find it over and over again

it"s like this in the company today

Today, in the company, I wrote a chat application through socket.io . As a result, the name of the triggered event was missing a letter. And looked for it for half an hour

it used to be like this

when writing WeChat Mini Programs"s payment, I encountered a parameter that was case-sensitive. Just because one letter Wechat requires all lowercase, and the first letter I passed is uppercase. Instead, it took a whole day to find out what the problem was

  • and more than N
  • A li that should not appear at all
  • low-level error
  • appears all the time
  • .
  • every time such a low-level error is found
  • can"t help but slap themselves in the mouth
  • however, it still doesn"t work

then

I would like to ask my fellow countrymen, how can this problem be avoided as far as possible?
is there a feasible way?
