JavaScript tanh function

JavaScript tanh function is a Math function used to calculate the trigonometry hyperbolic tangent for the specified expression. The syntax of the tanh function is:

Math.tanh(number);

We can use the below exp method to get the same result.

(Math.exp(number) - Math.exp(- number)) / (Math.exp(number) + Math.exp(- number))

JavaScript tanh Example

In this example, we find the JavaScript hyperbolic Tangent values for different data types and display the output.

HINT: Use EXP Function in JavaScript to achieve the same result.
