String Literals

  • A string literal is a sequence of one or more letters, numbers or punctuation marks, enclosed in double quotes (" ") or single quotes (' ').

  • Example- "This is my hashnode blog"

  • "June 28, 1998"

  • " "

  • "I am a frontend developer"

Boolean Literals

  • Boolean literal is very simple among all the literal data types because they have only one of two values: True or False.

  • They seem to be very simple but they are actually very useful because they have the ability to check whether the particular variable or condition is true or false.

  • You can assign a boolean literals directly to a variable, like this

  • Example- currentAge == "twenty-five"

  • This compares the expression currentAge == "twenty-five" It will check the value of a string "twenty-five" If the expression evaluates to be true it means the currentAge is "twenty-five".

  • If the expression evaluates to be false it means the currentAge is not "twenty-five".
