Using if..else, write the code which gets a number via prompt and then shows in alert:
1, if the value is greater than zero,-1, if less than zero,0, if equals zero.
In this task we assume that the input is always a number.
let value = prompt('Type a number', 0);
if (value > 0) {
alert( 1 );
} else if (value < 0) {
alert( -1 );
} else {
alert( 0 );
}
