You can use the following operators to compare two numbers, or two strings.
The operation returns a boolean.
<=minus than, or equal to
>=greater than, or equal to
const a = 2 a >= 1 //true
When comparing strings, those operators check for the letter ordering, encoded in Unicode. The bigger the letter value, the bigger the letter is to the operator when comparing.
You can find the list of Unicode Codes for characters on Wikipedia.
