Logarithm in Specific Base

Introduction

In this lab, we will be exploring the concept of logarithms in specific bases in JavaScript. We will learn how to calculate the logarithm of a given number in a specific base using the Math.log() function and some basic math operations. Through this lab, we will gain a better understanding of logarithmic functions and how to implement them in our JavaScript programs.

How to Calculate Logarithm in a Specific Base

To calculate the logarithm of a given number in a specific base, follow these steps:

1. Open the Terminal or SSH.
2. Type node to start practicing coding.
3. Use the following code to calculate the logarithm:

const logBase = (n, base) => Math.log(n) / Math.log(base);

4. Replace n with the given number and base with the specific base.
5. Run the code to get the result.

Here are some examples:

logBase(10, 10); // 1
logBase(100, 10); // 2
