In JS console.log(+'solo'+'learn'), why the output =NaNlearn

Answer 1

Adding + operator before an operand converts it to a positive integer. If the operand is not a number it returns NaN

So
+'solo' gives NaN
and
+'solo'+'learn' gives NaN+'learn

JavaScript automatically converts NaN to a string before concatenation. Hence the result.

I know what you are thinking and yes I agree implicit type conversion is confusing.

Actually don't no details. I just know operand + & - in font of a string converts it to number.

IF
+"2" = 2
-"2" = -2
+"hlw" = NaN
-"hlw" = NaN
