How to clear the javascript console programmatically?

Question

How we can clear the Console in Chrome, Firefox and other browsers. I've tried the following commands, but none is working:

Chrome: clear()

Firefox: console.clear()

Any ideas?

For every browser it is different so you can write some script so that it will work for different browsers. or you can use this script

console.API;

if (typeof console._commandLineAPI !== 'undefined') {
    console.API = console._commandLineAPI; //chrome
} else if (typeof console._inspectorCommandLineAPI !== 'undefined') {
    console.API = console._inspectorCommandLineAPI; //Safari
} else if (typeof console.clear !== 'undefined') {
    console.API = console;
}

console.API.clear();

so on for other browsers too.

Note: Successfully tested (after edit, 08/2016) in Safari v9.1 for Mac OS, and Chrome v52.0 for Mac OS

Note that this still doesn't work on chrome if _Preserve log_ is enabled. — NullDev, Jan 10 '18 at 11:46

In Firefox, as of July 25, 2019, I first tried typing:

console.API.clear();

But, that gave a message in the console that: console.API is undefined. So, smelling that something was probably right with the answer given above, but not exactly, I then typed the following in the console:

console.clear();

That worked, and the console was cleared and gave a message that the console had been cleared. I do not know if this would work in any other browser besides Firefox, and, of course, I only know that it worked today.

Coming 5 years later ;-) but if it's of any use, here it is the @govind-mantri brilliant answer, in TypeScript, avoiding the TSLint errors/hints:

    private clearConsole() {

        // tslint:disable-next-line: variable-name
        const _console: any = console;
        // tslint:disable-next-line: no-string-literal
        let consoleAPI: any = console['API'];

        if (typeof _console._commandLineAPI !== 'undefined') {                // Chrome
            consoleAPI = _console._commandLineAPI;

        } else if (typeof _console._inspectorCommandLineAPI !== 'undefined') { // Safari
            consoleAPI = _console._inspectorCommandLineAPI;

        } else if (typeof _console.clear !== 'undefined') {                    // rest
            consoleAPI = _console;
        }

        consoleAPI.clear();
    }

console.clear();

Using this in chrome console is clear but make sure preservelog is unchecked in console setting.
