How to log to the console if an error occurs using assert in Node.js

Answer 1

const errorMsg = " is not even";
for (let num = 2; num <= 6; num++) {
    console.log(`num = ${num}`);
    console.assert(num % 2 === 0, { num }, num + errorMsg);
}



/*
run:

num = 2
num = 3
num = 4
num = 5
num = 6

Assertion failed: [object Object] 3 is not even
Assertion failed: [object Object] 5 is not even
