Question on Oxoacids

So in the course reader it says that oxoacids lose H+ more readily if the resulting anion can be stabilized by electron withdrawing atoms.
I know from lecture that hypochlorous acid is stronger than hypoiodous acid because chlorine is more electron negative compared to iodone, but I dont' understand exactly why.
Can someone elaborate this?

An acid is more likely to dissociate if its conjugate base is stable. What needs to be stabilized on the conjugate base is a negative charge. If this negative charge can be dispersed more evenly through the molecule via electronegative atoms, then the conjugate base will be stabilized.
