var txt;

txt = "Math.E = " + Math.E + "<br>";
txt = txt + "Math.log(Math.E) = " + Math.log(Math.E) + "<br>";
txt = txt + "Math.log1p(Math.E - 1) = " + Math.log1p(Math.E - 1) + "<br>";

The output (value of txt) after running above script will be:

Math.E = 2.718281828459045
Math.log(Math.E) = 1
Math.log1p(Math.E - 1) = 1
