<= 表达式是什么意思？

Question

So I have seen something like the code below in a React-Redux application

return StartTime <= currentTime && currentTime <= EndTime;

What exactly does this line returns to? What does the <= mean?

Answer 1

It's the less than or equal to operator.

1 <= 2 // true
1 <= 1 // true
1 <= 0 // false

Answer 2

This is "less than or equal to" operator. Example:

return 3 <= 3 && 4 <= 5 //true&&true - true
return 3 <= 2 && 4 <= 5 //false&&true - false
