Truthy and Falsy

With type, every value has a boolean value called truthy or falsy value.

The following values are always falsy:

• false
• 0 (zero)
• '' or "" (empty string)
• null
• undefined
• NaN

Everything else is truthy. That includes:

• '0' (a string containing a single zero)
• 'false' (a string containing the text “false”)
• [] (an empty array)
• {} (an empty object)
• function(){} (an “empty” function)

double equal (==) vs triple equal (===)

Loose Equality Comparisons With( ==)only compares 2 values not the types of the values

2==”2”// returns true

Strict Equality Comparisons With (===) compares 2 values with their type.

2==”2”// returns false
