I need to figure out how to output a list of numbers in a loop to the console. However, the output to the console must be in the same line, as opposed cascading down the page with every new number. Below, I have two separate blocks of code that accomplish the same thing. One uses a while loop and the other uses a for loop. If there's a difference between being able to accomplish this in a for loop versus a while loop, I'd like to know that as well. Thank you.
While Loop
var number = 2;
while (number <=10) {
console.log(number++);
number = number + 1;
}
For Loop
for (var number = 2; number <= 10; number = number + 2)
console.log(number);
To keep it simple, all you need to do is concatenate the numbers to a string that you keep track of. Every time you console.log, it will automatically move it to a new line.
var output = "";
for (var i = 2; i <= 10; i = i + 2) {
output += i + " ";
}
console.log(output);
The type of loop you use doesn't matter.
While:
var number = 2, output = [];
while (number <=10) {
output.push(number++);
number = number + 1;
}
console.log.apply(console, output);
For:
var number, output=[];
for (number = 2; number <= 10; number = number + 2) {
output.push(number);
}
console.log.apply(console, output);
Note, I would recommend you don't do for(var x...
- it gives a false sense of scope for the var x - but that's just opinion on my part
