Understanding Logarithms
A logarithm is the inverse operation to exponentiation. The logarithm of a number x with respect to base b is the exponent to which b must be raised to produce x. Mathematically, if b^y = x, then log_b(x) = y.
The Math.log Function and Base Conversion
The Math.log() function in JavaScript returns the natural logarithm (base e) of a number. To calculate logarithms with different bases, we use the change of base formula: logb(x) = logk(x) / log_k(b), where k is usually e or 10.
