I am learning ES6, so bear me please.

Following is the code which is running fine, if I click the Run button one time, but on second hit it starts showing TypeError: redeclaration of let myArr error.

Let me know about this weird (may be not) behavior.

let myArr = [34,45,67,2,67,1,5,90];

let evenArr = [];

let oddArr = [];

myArr.forEach(x => {

    if (x % 2 === 0) {

        evenArr.push(x);

    } else {

        oddArr.push(x);

    }

});



console.log(evenArr);

console.log(oddArr);

Error -
