| 2. 1. 2. Arithmetic Operators (+) |
|
|
All the common arithmetic operators will attempt to convert strings to numbers when applicable. |
If a string cannot be converted to a number, NaN (Not A Number) will be returned. |
Addition (+) |
If the values on either side are numerical values, the values are added together. |
IF the values are strings, they are concatenated together. |
The following line of code |
|
var resultOfAdd = 34 + 12;
|
|
would set the variable resultOfAdd equal to 46 |
|
var resultOfAdd = "a" + "b";
|
|
would set the variable resultOfAdd equal to the string "ab". |
