Hi, I have posted this question before but the solution am getting is not what I want.
Note:
Please follow the instructions I posted before the question, let me know if there is an issue.
Instruction:
Please write these problems in javascript.
1. You are to have two javascript files:
a. your problem javascript and
b. your test javascript file that verifies the function that was written in your problem javascript
2. The implementation for your 5 JavaScript functions must be completed within your - problems.js file.
3. Your Problem JavaScript functions file must be configured for strict mode (“use strict”)
The pages that follow provide the description of the 5 JavaScript functions that you must implement
Questions
1. Description
a). You are to develop a JavaScript file (problems.js) that contains the implementation of 5
functions. Each function is represented as one step,
b). Each function is independent and solves a unique problem, as such, treat and implement each function in isolation of the others, that is, you should only focus on one problem at a time.
2). Objective
• Write decision-making statements and control structures to solve problems
• Apply
• Testing and debugging
3. Please ensure to remove all instances of the following from your final submission solution:
• document.write()
• innerHTML()
• alert()
• any commented code
• Do not overuse the console log, spamming the console log unnecessarily
![Function 4: Class Grading
function _four( array )
Create a JavaScript function that meets the following requirements:
Receives a variable length array of numbers, representing student grades in a course
The function traverses the array to determine the number of passing and failing grades.
A passing grade, is grade greater than or equal to 50
The function displays the count (console log) for the number passing grades, failing grades and overall
class average as illustrated below
Average class grade is rounded to 1 decimal point
The function returns the array containing the number of passing grades, the number of failing grades, and
the overall averages of the grades, respectively, back to the caller
Calling _four([50,51,80,45])
The number of passing grades: 3, failing grades: 1, and class average: 56.5
Calling _four([35,45,25,10,6,33])
The number of passing grades: 0, failing grades: 6, and class average: 25.7
Calling _four([80,90])
The number of passing grades: 2, failing grades: 0, and class average: 85.0](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faea484e9-46e6-4eaf-9b67-c167b4ca38e3%2Faad14d6d-44e3-46ca-9fef-cd334449109a%2Fun87eig6q_processed.png&w=3840&q=75)
