How to make better this 'cut string array' function?

Question

Hi there! I'd like to see better ways to make the code below...

function cutIt(){
strArray = prompt("Write a String Array comma separated please");
if(strArray){
strArray = strArray.split(",");
let strMinLength = strArray[0].length;
strArray.forEach(element => {
if(element.length < strMinLength ){ strMinLength = element.length }
});
let choppedArr = [];
strArray.forEach( el => { choppedArr.push( el.slice( 0,strMinLength )) });
alert("Minimum strings's length is " + strMinLength + ", so the new chopped array is " + choppedArr );
}
}

I really liked the way how they are teaching JavaScript at codewars.

I couldn't find much improvement other than doing trimming and finding minStrLength in same loop. There are Scopes of few performance improvement by using for loop instead of forEach.

I am curious to see other alternatives as well.
