Changelist

This project is about starting to learn how to use methods in JS, and using the console on the browser, at some point, my branch remotely and locally lost the connection, so I ran from my terminal git branch --unset-upstream and then
git push -u origin coursework/sprint-1 to link the branches.

Questions

Do you have any recommendations for learning how to use Git more deeply, especially when we want to go back in history and keep only a specific part in the head of my branch?

Basically, a surgery choosing a specific part to bring back from historical commits.

…operations

…d using and alert.

… methods like substring and padStart to add and take part or the string

…e operator.

Sprint-1/1-key-exercises/2-initials.js

+
+const initials = firstName.charAt(0) + middleName.charAt(0) + lastName.charAt(0);
+console.log( `acronym = ${initials}`);
+


Nicely done. It might be better practice to stick with the variable declaration format already provided.

Theoreoluwa · 2026-02-14T00:58:26Z

Sprint-1/1-key-exercises/3-paths.js

+
+
+console.log(`The dir is 👉 ${dir}`);
+console.log(`The nameFile is 👉 ${fileName}`);


It's good practice to infuse an additional variable into your task. Well done.

Theoreoluwa · 2026-02-14T01:01:31Z

Sprint-1/1-key-exercises/4-random.js

+Math.floor() //removes decimal part and returns whole number
+Math.random() //needs to values between minimum and maximum to generate a random number
+
+console.log(maximum - minimum + 1 ) + minimum; // this is same as 100 - 1 + 1 = 100 
+console.log(`The random number is ${num}`);


You need to do more in following the given task instruction. Is there a way you could have broken down the flow of the code more? Rather than focusing on just highlighting the math object, why not expatiate on how the equation is solved to arrive at the value in the num variable.

Sprint-1/2-mandatory-errors/3.js

+const numberString = cardNumber.toString();
+const last4Digits = numberString.slice(-4);
+const num = Number(last4Digits);
+
+console.log(num);


Very good implementation and variable naming convention.

Theoreoluwa · 2026-02-14T01:15:37Z

Sprint-1/3-mandatory-interpret/1-percentage-change.js

+    // There are 6 function calls in this file:
+    // Line 5: carPrice.replaceAll(",", "")
+    // Line 5: Number(carPrice.replaceAll(",", ""))
+    // Line 6: priceAfterOneYear.replaceAll(",", "")    
+    // Line 6: Number(priceAfterOneYear.replaceAll(",", ""))
+    // Line 10: console.log(`The percentage change is ${percentageChange}`) this is also 
+    // a function call to log the output as string to the console, then call the var percentageChange 


Can you have a look at the number of function calls again and if you are sure, provide a little textual explanation for your reasoning.

Theoreoluwa · 2026-02-14T01:19:02Z

Sprint-1/3-mandatory-interpret/2-time-format.js

+    //result stores the variables of totalHours, remainingMinutes and remainingSeconds in a string format readable time clock "H:M:S"
+    //A better name for this variable could be MovieDuration


Great contextual naming convention

Sprint-1/4-stretch-explore/chrome.md

+    📢 The message you pass to alert() is displayed to the user.
+
+    ⏸️ JavaScript execution pauses until the user clicks OK.
+
+    🚫 The user can’t interact with the page while the alert is open (it blocks the UI).
+
+


Great and detailed response

Theoreoluwa · 2026-02-14T01:23:32Z

Sprint-1/4-stretch-explore/chrome.md

 Now try invoking the function `prompt` with a string input of `"What is your name?"` - store the return value of your call to `prompt` in an variable called `myName`.

+
+    let myName = prompt("hello what is your name")
+    alert("hi " + myName)
+
+    The prompt function displays a modal dialog that captures user input. The value entered is stored in myName, and alert then displays a greeting that includes that value.
+
+
 What effect does calling the `prompt` function have?
 What is the return value of `prompt`?
+
+    Calling the prompt() function displays a modal pop-up dialog that:
+
+    * Shows a message to the user
+
+    * Includes a text input field
+
+    * Has OK and Cancel      buttons
+
+    * Blocks interaction with the page until the user responds
+


Are there ways to improve your implementation to follow the acceptance criteria for the tasks? Read through it and practise again. I'm sure you will get new insights

Sprint-1/exercises/decimal.js

+
+// Create a variable called wholeNumberPart and assign to it an expression that evaluates to 56 ( the whole number part of num )
+// Create a variable called decimalPart and assign to it an expression that evaluates to 0.5678 ( the decimal part of num )
+// Create a variable called roundedNum and assign to it an expression that evaluates to 57 ( num rounded to the nearest whole number )
+
+// Log your variables to the console to check your answers
+
+
+const wholeNumberPart = Math.floor(num);
+console.log(` Whole number = ${wholeNumberPart}`);
+
+const decimalPart = num - wholeNumberPart;
+console.log(` Decimal part = ${decimalPart.toFixed(4)}`); // toFixed(4) to show 4 decimal places instead of whole number
+
+console.log(`type of parameter = ${typeof(wholeNumberPart)}`); //confirm that decimalPart is a number
+
+const roundedNum = Math.round(num); // rounds to nearest whole number
+console.log(` Rounded number = ${roundedNum}`);


It's good practice to involve some new tasks for yourself to improve your skills.
