In my code, I am utilizing the JavaScript function join("") to convert a character array into a string while removing comma separators between characters. Typically, this method works flawlessly, but recently I encountered an issue when there is a "less than" character (<) in the array.
For instance:
var chararray = ["A", "B", "C", "D", "E"];
var string = chararray.join("");
console.log(string);
This produces the expected result of ABCDE
However, in another scenario, it does not behave as anticipated:
var chararray = ["A", "B", "C", "<", "E"];
var string = chararray.join("");
console.log(string);
In this case, the output is incorrectly ABC (it stops at the "<" character)
If I retain the commas by using join() without parameters, it functions correctly:
var chararray = ["A", "B", "C", "<", "E"];
var string = chararray.join();
console.log(string);
This outputs A,B,C,<,E
Yet, attempting to remove the commas using string.replace(/,/g, "") yields the same outcome - ABC
var chararray = ["A", "B", "C", "<", "E"];
var string = chararray.join();
var outputstring = string.replace(/,/g, "");
console.log(outputstring);
This results in ABC once more, stopping at the "<" symbol.
My puzzlement stems from the fact that, as far as I know, "<" should not pose a problem in JavaScript unless used within a mathematical or comparison equation. This odd behavior only occurs with this particular character, not with symbols like > or =.
