Arrays also have a .shift() method. This will remove the first element of the array, unlike .pop() which removes the last element. Here is an example of the .shift() method:
const numbers = [1, 2, 3];
numbers.shift();
The numbers array would be [2, 3].
Directly below your numbers array, declare a shifted variable and assign it the result of calling .shift() on the numbers array. On the next line, log the shifted variable to the console.
You should use const to declare a shifted variable.
assert.match(__helpers.removeJSComments(code), /const\s+shifted/);
You should call .shift() on your numbers array.
assert.deepEqual(numbers, [5, 2, 3]);
You should assign the result of your .shift() call to your shifted variable.
assert.equal(shifted, 1);
You should log your shifted variable.
assert.match(__helpers.removeJSComments(code), /console\.log\(\s*shifted\s*\)/);
const character = "#";
const count = 8;
const rows = [];
function padRow(rowNumber, rowCount) {
return " ".repeat(rowCount - rowNumber) + character.repeat(2 * rowNumber - 1) + " ".repeat(rowCount - rowNumber);
}
// TODO: use a different type of loop
/*for (let i = 1; i <= count; i++) {
rows.push(padRow(i, count));
}*/
/*while (rows.length < count) {
rows.push(padRow(rows.length + 1, count));
}*/
/*for (let i = count; i > 0; i--) {
rows.push(padRow(i, count));
}*/
