Set a dynamic interval with JS. This example shows a growing interval for logs.

dynamicSetInterval.js

const dynamicSetInterval = (func, getInterval) => {
    setTimeout(() => {
        func();
        dynamicSetInterval(func, getInterval);
    }, getInterval());
};


let currentInterval = 1000; // 1 second
const maxInterval = 1000 * 60 * 3; // 3 minutes
const growthFactor = 1.5;
dynamicSetInterval(() => console.log('hi', new Date().getTime()),  
                   () => {
                          currentInterval = Math.min(currentInterval * growthFactor, maxInterval);
                          return currentInterval;
                    }
);

Plotting the outputs show:
