In a web application I used many console.logs for printing information on console. I want the timestamp of each console.log

Question

I have a web application in which I have used many console.logs that are printing required information on console. I want the timestamp of each console.log to identify which console.log called exactly when. Is there is any general method by which we can do it?

For this should I go manually in and add the time stamp in each console.log or there is any method by which we can do it?

Answer 1

On Chrome, there's a setting that allows you to do it.

If you want to do it via JavaScript, there's a nice implementation:

console.log2 = console.log.bind(console);

console.log = function(...msg) {
    const stamp = `[${Date.now()} ]`;
    this.log2(stamp, ...msg);
};

Answer 2

How about using Date?

let i = 0;

setInterval(() => console.log(Date(), `=> message ${++i}`), 1000);

or write a wrapper as this answer suggests. I'd prefer not to redefine console.log in favor of:

const log = (...msgs) => console.log(Date(), ...msgs);

log("hey!");

Answer 3

The simplest way is appending new Date() to console.log like,

console.log("You console message. Timestamp = ",new Date());
