Takes in a linkedList and returns true if the circular loop starts anywhere in the list.
Example 1: (linkedList starts at n1)
const n1 = { val: 'n1Val', };
const n2 = { val: 'n2Val', };
const n3 = { val: 'n3Val', };
n1['next'] = n2;
n2['next'] = n3;
n3['next'] = n2;
Input: n1
Output: true because the circular loop started somewhere in the list.
Example 2: (linkedList starts at n1)
const n1 = { val: 'n1Val', };
const n2 = { val: 'n2Val', };
const n3 = { val: 'n3Val', };
const n4 = { val: 'n4Val', };
n1['next'] = n2;
n2['next'] = n3;
n3['next'] = n4;
n4['next'] = n2;
Input: n1
Output: true because the circular loop started somewhere in the list.
Example 3: (linkedList starts at n1)
const n1 = { val: 'n1Val', };
const n2 = { val: 'n2Val', };
const n3 = { val: 'n3Val', };
n1['next'] = n2;
n2['next'] = n3;
Input: n1
Output: false because the circular loop does not start somewhere in the list.

Output: 10
Input: a string, a number (n)
return: the string repeated n times.
Input: "Apple",5
return: Apple Apple Apple Apple Apple
Takes in an object and a function and calls the function as many times as there are key/value pairs with each key, value. It's like you're creating a forEach function for objects. For each key/value pair in the object, you'll be doing calling the function to each of those key/value pairs. Also, map is a native method in Javascript which means doing the same thing to every element in the array. So you're essentially writing a map method for objects!
const obj1 = {
name: 'Maricris',
age: 24,
};
const func1 = (key, value) => {
console.log(`Key/Value Pair = ${key}: ${value}`);
};
Input: (obj1, func1)
Output:
Key/Value Pair = Name: Maricris
Key/Value Pair = Age: 24
const obj2 = {
curriculum: 'HTML',
challenges: 3,
students: 'Kinue + Saumya +Amey',
level: 5,
};
const func2 = (key, value) => {
console.log(`Key/Value Pair = ${key}: ${value}`);
};
Input: (obj2, func2)
Output:
Key/Value Pair = curriculum: HTML
Key/Value Pair = challenges: 3
Key/Value Pair = students: Kinue + Saumya + Amey
Key/Value Pair = level: 5
Input: a string, a character
Output: return true or false
Example:
Input: 'hello', 'e'
Output: true
Example:
Input: 'world', 'a'
Output: false
Input: ObjectA, function
Output: ObjectC
Example:
Input: {5: "blah blah", name: "ho", zolo: "4thech"}, (k, v) => {return v.length > 3}
Output: {5: "blah blah", name: "ho", zolo: "4thech"}
Input: a Function, a number, a number
input: fun(), 4, 5
Output : fun(1) fun(2) fun(3) fun(4) fun(5)
Takes in an array of numbers and returns an array of all duplicate numbers. Hint: Use an object to keep track of which numbers are repeated.
Input: [1, 2, 2, 3, 3, 3, 4, 5, 5]
Output: [2, 3, 5]
Input: a function, a number
Input: fun() , 2
output: fun(), fun()
INPUT: number, number, number
RETURN: the biggest one.
INPUT: 5,8,9
RETURN: 9
Inputs:

const a = { val: 1, next: b };
test(a, false);
test(b, false);
Input: a function, a number
Input: fun(),4
Return: fun() fun() fun() fun() //returning the function every second for 4 seconds //
Input: number
Output: array
Examples:
Input: 7
Output: 1, 2, 3, 5, 7
