使用 FOR 循环将字符串推入空数组

Question

The goal is to input a string "Item" into myArray with the function and input it the number of times that I indicate in the function arrayFiller parameter. Here's what I have so far. I am still new to FOR loops so I'm not sure what to put into the next two parameters in the FOR loop. I'm guessing that I will need to use the .push object at some point but I've been trying this particular problem for so long.

myArray = [];

function arrayFiller(times) {
 for (i = 0;     ;i++)
 myArray.push[i];
}

arrayFiller(2);

arrayFiller(5) should add five different strings of "Item" in the empty array.

Answer 1

• .push is a method, so you need to use ( and ) to pass it the value to push into the array, not [ and ] .
• You didn't configure your loop to have a looping condition.
• You never wrote any code to inspect the array after the operation to know if it worked.
• Your code simply inserts the looping counter value into the array. If you want something else (like "item"), you'd have to add that.

 myArray = []; function arrayFiller(times, item) { for (i = 0; i < times; i++) myArray.push("Item"); } arrayFiller(5); console.log("# of items in array: " + myArray.length, myArray); myArray.length = 0; // Reset array arrayFiller(2); console.log("# of items in array: " + myArray.length, myArray);
