Example

const foo = {
    bar: {
        baz: true
    }
}

dotObj('foo.bar.baz', foo); // true

Group By

Group items by the key returned in the callback.

const data = [
    { id: 'a' },
    { id: 'b' },
    { id: 'a' }
];

Recursively clone an object.

Usage

const obj = {
    foo: 'bar'
}

cloneObj(obj);

Checks if a given word is a palindrome.

Usage

const tests = ['hannah', 'anna', 'kayak', 'apple', 'mom', 'wow', 'rotator', 'radar']

tests.forEach((test) => {
    console.log('IS_PALINDROME', test, isPalindrome(test));
});

Password Entropy

Calculate the entropy of a password.

Usage

const passEnt = require('passEnt');

const H = passEnt('pswd'); // 18.801758872564367
