You can group comparison operations using the
&&
operator, which is a logical AND.
In the following example, if the variable
num
is greater than zero and
simultaneously is less than 10
,
only then '+++'
will be displayed:
let num = 3;
if (num > 0 && num < 10) {
console.log('+++');
} else {
console.log('---');
}
Conditions can be imposed not on one variable,
but on different ones. In the following example,
if the variable num1
is equal to 2
and simultaneously the variable num2
is
equal to 3
, only then the condition
will be true:
let num1 = 2;
let num2 = 3;
if (num1 == 2 && num2 == 3) {
console.log('+++');
} else {
console.log('---');
}
Check that the variable num
is
greater than zero and less than 5
.
Check that the variable num
is
greater than or equal to 10
and
less than or equal to 20
.
Check that the variable num1
is
equal to or less than 1
and the
variable num2
is greater than or
equal to 3
.
