increase frequency of sine wave over time in web audio api

increaseSineFrequencyOverTime.js

function increaseFreq(osc, nOfTimesToIncreaseFreq, delayInSeconds, riseInFrequency){
    for(let i = 0; i < nOfTimesToIncreaseFreq; i++){
         osc.frequency.setValueAtTime(200 + (i*riseInFrequency) , audioCtx.currentTime + (i * delayInSeconds)); // value in hertz
    }

oscillator.start();
