Infinite loop

Question

Can someone explain why this piece of code is considered an infinite loop and how it shall be corrected ?

var check = true;
var loopCheck = function(check){
while(check){
console.log("Looped once!");
____________
}
}

Answer 1

The loop continues until the condition is false.

while(check){
...log("Stuff");
}
check is true!
So, that loop is infinite since the condition is always true.

We can stop the loop a couple ways.

For one, since we're using a variable we can make check false.

while(check){
...log("Stuff");
check = !check; // can also write false
}

Or, we can use a break; to exit the loop.

while(check){
..log("stuff");
break;
}

Answer 2

The while loop continues to loop while the condition passed to it returns true. As you have not defined a condition in which check is false and you have set it to true by defult, check will always return true and thus the loop will never end.
