The use of comparison operators (<, <=, >=, >) with strings is not likely to yield
the expected results. Make sure the intention was to compare strings and not numbers.
Noncompliant code example
var appleNumber = "123";
var orangeNumber = "45";
if (appleNumber < orangeNumber) { // Noncompliant, this condition is true
alert("There are more oranges");
}
Compliant solution
var appleNumber = "123";
var orangeNumber = "45";
if (Number(appleNumber) < Number(orangeNumber)) {
alert("There are more oranges");
}
Exceptions
The rule ignores string comparisons occurring in the callback of a sort invocation, e.g.:
const fruits = ['orange', 'apple', 'banana'];
fruits.sort((a, b) => a < b);
