Exploring the Core of true value vs false value in JavaScript...

Truthy Value

In JavaScript, a truthy value is any value that is considered true when evaluated in a Boolean context. Values that are not falsy are considered truthy.

Example of truthy values:

• Any non-zero number (1,-5,3.14)
• Non-empty strings ("hello" )
• space value(" ")
• Objects ({}, [])
• The boolean true

Now Example,

1.Checking a Non-empty String:

• Explanation: The string "JavaScript" is a non-empty string, so it evaluates to true.

2.Checking a String with a Space:

• Explanation: The string " " (a string containing a space) is also a non-empty string, which evaluates to true.

3.Checking a Positive Number:

• Explanation: The number 100 is a non-zero number, so it evaluates to true.

4.Checking a Negative Number:

• Explanation: The number -5 is also a non-zero number, making it truthy.

5.Checking an Empty Array & Object:

• Explanation: An empty array [] is considered truthy in JavaScript.
• Explanation: An empty object {} is also considered truthy

6.Checking the Boolean True:

• Explanation: The boolean value true is, by definition, truthy.

Falsy Value

A falsy value is something which evaluates to FALSE, for instance when checking a variable.

Example of falsy values:

• 0 zero && (-0) negative zero
• empty strings ("" )
• null,undefine & Nan
• The boolean false
