How to do simple operators in JS

Use the “+” operator to add two numbers in JavaScript

Use the “-“ operator to subtract two numbers in JavaScript

Use the “*” operator to multiply two numbers in JavaScript

Use the “/” operator to divide two numbers in JavaScript

Use the “%” operator to get the remainder of a division operation in JavaScript

Iterating

Iteration is going through a set of laws or objectives for the loops to complete. This allows for the desired objective to be completed.

Randomization

Randomization is used to generate a random number. For example, RANDOM(a,b) would generate any number from a to b. Each result from randomization is equally likely to occur. Each execution might produce a different result.

How to find the mean in JS

```javascript // Define an array var arry = [4, 62, 3, 38];

// Define a function to calculate the mean using an inputted array function calculateAverageOfArray(array) { var total = 0; var count = 0;

// Add all the values of the array
jQuery.each(arry, function(index, value) {
    total += value;
    count++;
});

// Take the sum of the array and divide it by the length of the array
return total / count; }

console.log(“The average of your list is “ + calculateAverageOfArray(arry));
