JavaScript(JS) math method - tanh

The tanh method in JavaScript's Math object returns the hyperbolic tangent of a given number. The tanh method takes one argument, which is the number to calculate the hyperbolic tangent of.

Here's an example usage:

const num = 1;
const hyperbolicTangent = Math.tanh(num);
console.log(hyperbolicTangent); // 0.7615941559557649

In the above example, the Math.tanh method is used to calculate the hyperbolic tangent of the number 1. The result, which is 0.7615941559557649, is then logged to the console.
