Challenge: Compare Variables in JavaScript

Task

We have three variables in this task: a = 33, b = 26, and c = "26". We will perform various comparing operations on these variables.

  1. Check if a is equal to b.
  2. Check if b is strictly equal to c.
  3. Determine if a is greater than or equal to c.
  4. Find out if b is less than c.
  5. Check if a is greater than b AND if b is equal to c.
  6. Check if a is equal to b OR if c is less than a.

              
12345678910

            
let a = 33;
let b = 26;
let c = "26";

console.log(a ___ b); // Task 1
console.log(b ___ c); // Task 2
console.log(a ___ c); // Task 3
console.log(b ___ c); // Task 4
console.log(a ___ b && b ___ c); // Task 5
console.log(a ___ b || c ___ a); // Task 6
copy

The output should be:

python
  1. Use the comparison operators: ==, ===, >=, <, >.
  2. Use the logical operators: AND (&&) and OR (||).

              
12345678910

            
let a = 33;
let b = 26;
let c = "26";

console.log(a == b); // Task 1
console.log(b === c); // Task 2
console.log(a >= c); // Task 3
console.log(b < c); // Task 4
console.log(a > b && b == c); // Task 5
console.log(a == b || c < a); // Task 6
copy

Was alles duidelijk?
