JavaScript(JS) math method - asinh

The asinh method in JavaScript's Math object returns the hyperbolic arcsine of a number.

The hyperbolic arcsine function, also known as the inverse hyperbolic sine function, is the inverse function of the hyperbolic sine function. It is defined as:

asinh(x) = ln(x + sqrt(x^2 + 1))

The asinh method takes one argument, which is the number whose hyperbolic arcsine needs to be calculated. If the argument is not a number, it will be converted to one before the calculation. If the argument is NaN or infinite, NaN will be returned.

Here's an example usage:

const x = 3;
const asinhX = Math.asinh(x);
console.log(asinhX); // 1.8184464592320662

In the above example, the hyperbolic arcsine of 3 is calculated using the Math.asinh method and assigned to the asinhX variable. The result is then logged to the console.
