Splitting a string by newline character succeeds but removes the last character from the string

I am trying to split a string by newline character (\n) but it removes the last character from the string. How do I rectify this?

I have tried replacing the newline character with a pair of the same then splitting .. but not working.

var lines = str.split("\n");

The screenshot shows the difference between the raw array which I use to get the string at the console and the display in the table. As indicated by the marks, the last letters are missing:
