- Truthy and Falsy Values:
As we all know if a value is determined as ‘True’ or ‘False’ then it is called a Boolean value. There are also some values that are actually not boolean values but they behave like one.
In that case, these values are called ‘Truthy’ or ‘Falsy’ values. if the values act as ‘True’ it is then called ‘Truthy’. On the contrary, if it behaves like a ‘False” value it is known as a ‘Falsy’ value.
Falsy values:
a. False.
b. NAN
c. Null.
d. Undefined.
e. 0
f. “”
These are ‘Falsy’ values.
Truthy Values:
a. True.
b. [] ( empty array)
c. Any Number.
These are ‘Truthy’ values.
