setInterval(function(),time) change time on runtime

Question

I want to change setInterval function time when my code is running.

I try this

Answer 1

timer = setInterval(come, 0); // zero isn't a valid interval...

You probably wants:

come();
timer = setInterval(come, 10000);

docs on MDN:

delay is the number of milliseconds (thousandths of a second) that the setInterval() function should wait before each call to func. As with setTimeout, there is a minimum delay enforced.

And:

Historically browsers implement setTimeout() "clamping": successive setTimeout() calls with delay smaller than the "minimum delay" limit are forced to the use at least the minimum delay. The minimum delay, DOM_MIN_TIMEOUT_VALUE, is 4 ms (stored in a preference in Firefox: dom.min_timeout_value), with a DOM_CLAMP_TIMEOUT_NESTING_LEVEL of 5ms.
