combine two expressions in one overshoot and anticipation

[anouab19920213]

i have this overshoot expression :

MaximumAmplitude = .1;
Frequency = 1.0;
Decay = 4.0;

n = 0; if (numKeys > 0){n = nearestKey(time).index;
	if (key(n).time > time){n--;}}
if (n == 0){ t = 0;}
else{t = time - key(n).time;}
if (n > 0){v = velocityAtTime(key(n).time - thisComp.frameDuration/10);
	if (t < 2){value + v*MaximumAmplitude*Math.sin(Frequency*t*2*Math.PI)/Math.exp(Decay*t)}
else{value;}}
else{value}

and i have this anticipation expression 

var PeriodForElastic = 0.8;
var AmplitudeForElastic = 50;
var OvershootAmount = 1.70158;

function easeandwizz_inBack(t, b, c, d) 
{return c*(t/=d)*t*((OvershootAmount+1)*t - OvershootAmount) + b;}
function easeAndWizz() {var n = 0;if (numKeys > 0) {n = nearestKey(time).index;
	if (key(n).time > time)	{ n-- }}
try {var key1 = key(n);var key2 = key(n+1);} 
catch(e) {return null;}var dim = 1;
try {key(1)[1];dim = 2;key(1)[2];dim = 3;} 
catch(e) {}t = time - key1.time;d = key2.time - key1.time;sX = key1[0];eX = key2[0] - key1[0];
if (dim >= 2) {sY = key1[1];eY = key2[1] - key1[1];
	if (dim >= 3) {sZ = key1[2];eZ = key2[2] - key1[2];}}
if ((time < key1.time) || (time > key2.time)) {return value;} 
else {val1 =  easeandwizz_inBack(t, sX, eX, d, AmplitudeForElastic, PeriodForElastic, OvershootAmount);
	switch (dim) {case 1:return val1;break;
		case 2:val2 = easeandwizz_inBack(t, sY, eY, d, AmplitudeForElastic, PeriodForElastic, OvershootAmount);return [val1, val2];break;
		case 3:val2 = easeandwizz_inBack(t, sY, eY, d, AmplitudeForElastic, PeriodForElastic, OvershootAmount);val3 = easeandwizz_inBack(t, sZ, eZ, d, AmplitudeForElastic, PeriodForElastic, OvershootAmount);return [val1, val2, val3];break;default:return null;}}}(easeAndWizz() || value);

i want to combine them to use it on one layer and have both anticipation and overshoot 

is that possible ??

Nb : if u have another expression that already dose both anticipation and overshoot  that will be more ideal!

Sure it's possible, but this will take some time to clean up the source code and consolidate the functions.

I think you've asked this on the Reddit AE forum too.  Looks like long time user Attilla has posted a solution:

I'm adding this link here in case any else is trying to do similar.
