Calculates the logarithm of the given number in the given base.
|
|
|
|
- Use `Math.log()` to get the logarithm from the value and the base and divide them.
|
|
|
|
```js
|
|
const logBase = (n, base) => Math.log(n) / Math.log(base);
|
|
```
|
|
|
|
```js
|
|
logBase(10, 10); // 1
|
|
logBase(100, 10); // 2
|
|
```
