var funcs = [];
for (let i = 0; i < 3; i++) { // let's create 3 functions
 funcs[i] = function() { // and store them in funcs
 console.log("My value: " + i); // each should log its value.
 };
}
for (var j = 0; j < 3; j++) {
 funcs[j](); // and now let's run each one to see
}

Till ES5, This problem can only be solved using closure.

But now in ES6, we have block level scope variables. Changing var to let in first for loop will solve the problem.
