The indexof in JavaScript and the wording of if judgment

General IndexOf and if-judging notation:

1 if ("112233". IndexOf (">-1"){2     console.log ("very two"); 3 }else  {4     console.log ("Why not Two"); 5 }

Whether the above code is our usual writing JS logic when the most commonly used to write, do you feel a bit out? Take a look at the following loading force notation (PS: Big god Please ignore)

1 if (~ "112233". IndexOf ("(")) {2     console.log ("very two"); 3 }else  {4     console.log ("Why not Two"); 5 }

Lying trough, obviously is the same code, do not bully Labor to read less.

Sao year, please pay attention to indexof front of "~", this goods is only bit operation take counter, here but can be used to install force. (Installed forcing Dafa:-1 to 0,0 in if judgment inside false)

With the introduction of the top-forcing Dafa, did you learn about the year?
