How to use OR condition in a JavaScript IF statement

Question

I understand that in JavaScript you can write   if  A  amp  amp  B    do something     But how do I implement an OR such as   if  A OR B    do something

Just use     if  A    B    your action here     Note  with string and number  It s more complicated   Check this for deep understading

One can use regular expressions  too    x000D   x000D  var thingToTest    B   x000D  if   A B  test thingToTest   alert  Do something    x000D   x000D   x000D    Here s an example of regular expressions in general    x000D   x000D  var myString    This is my search subject  x000D  if   my  test myString   alert  Do something here    x000D   x000D   x000D    This will look for  my  within the variable  myString    You can substitute a string directly in place of the  myString  variable   As an added bonus you can add the case insensitive  i  and the global  g  to the search as well    x000D   x000D  var myString    This is my search subject  x000D  if   my ig test myString   alert  Do something here    x000D   x000D   x000D

Worth noting that    will also return true if BOTH A and B are true   In JavaScript  if you re looking for A or B  but not both  you ll need to do something similar to   if   A  amp  amp   B      B  amp  amp   A

If we re going to mention regular expressions  we might as well mention the switch statement    x000D   x000D  var expr    Papayas   x000D  switch  expr    x000D    case  Oranges   x000D      console log  Oranges are  0 59 a pound     x000D      break  x000D    case  Mangoes   x000D    case  Papayas      Mangoes or papayas x000D      console log  Mangoes and papayas are  2 79 a pound     x000D         expected output   Mangoes and papayas are  2 79 a pound   x000D      break  x000D    default  x000D      console log  Sorry  we are out of     expr         x000D    x000D   x000D   x000D
