for
loop. This code will output each element of the array arr
to the console:
var arr = [10,9,8,7,6];Remember that Arrays have zero-based numbering, which means the last index of the array is length - 1. Our condition for this loop is
for (var i = 0; i < arr.length; i++) {
console.log(arr[i]);
}
i < arr.length
, which stops when i
is at length - 1.
total
to 0
. Use a for
loop to add the value of each element of the myArr
array to total
.
total
should be declared and initialized to 0
testString: assert(code.match(/(var|let|const)\s*?total\s*=\s*0.*?;?/), 'total
should be declared and initialized to 0');
- text: total
should equal 20
testString: assert(total === 20, 'total
should equal 20');
- text: You should use a for
loop to iterate through myArr
testString: assert(code.match(/for\s*\(/g).length > 1 && code.match(/myArr\s*\[/), 'You should use a for
loop to iterate through myArr
');
- text: Do not set total
to 20 directly
testString: assert(!code.match(/total[\s\+\-]*=\s*(0(?!\s*[;,]?$)|[1-9])/gm), 'Do not set total
to 20 directly');
