All falsey values in JavaScript

Question

What are the values in JavaScript that are \'falsey\', meaning that they evaluate as false in expressions like if(value), value ?

Answer 1

Just to add to @user568458's list of falsy values:

• In addition to integer number 0, the decimal number 0.0, 0.00 or any such zeroish number is also a falsy value.

  var myNum = 0.0;
  if(myNum){
      console.log('I am a truthy value');
  }
  else {
      console.log('I am a falsy value');
  }
  

  Above code snippet prints I am a falsy value

• Similarly hex representation of the number 0 is also a falsy value as shown in below code snippet:

  var myNum = 0x0; //hex representation of 0
  if(myNum){
      console.log('I am a truthy value');
  }   
  else {
      console.log('I am a falsy value');
  }
  

  Above code snippet again prints I am a falsy value.
