console.log(Math.log1p(1));
// expected output: 0.6931471805599453
console.log(Math.log1p(0));
// expected output: 0
console.log(Math.log1p(-1));
// expected output: -Infinity
console.log(Math.log1p(-2));
// expected output: NaN
Math.log1p(1); // 0.6931471805599453
Math.log1p(0); // 0
Math.log1p(-1); // -Infinity
