How to learn about blocking threads of execution in node.js?

Question

Node.js

Good day.
I want to create a module that will notify me about blocking the execution thread for a certain period of time, and would write about it to the console.
I don't even know where to start. How to determine that a blockage has occurred? So what would it look like in code? Please help with advice or literature, tell me, thanks in advance

Answer 1

Thread blocking will look like a long execution of some function, code section

function test() {
    while (true) {
      // calc
    }
  }

  test()
