In JavaScript, you can use this code to log the temperature for each day of the week:

js
 
 
Copy code
const weekdays = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'];

weekdays.forEach(day => {
  console.log(`Temperature on ${day} is 18 degrees`);
});

This loop will log a sentence for every day of the week to the console.

By using the weekdays array, the code will automatically loop through each day of the week and print a sentence with the specified temperature.

In JavaScript, you can console log multiple properties of an object using Object.entries() together with for...of:

javascript
 
 
Copy code
const myObject = {
  property1: "value1",
  property2: "value2"
};

for (const [key, value] of Object.entries(myObject)) {
  console.log(`${key}: ${value}`);
}

// Output:
// property1: value1
// property2: value2

You can also use Object.values() with for...of:

javascript
 
 
Copy code
const myObject = {
  property1: "value1",
  property2: "value2"
};

for (const value of Object.values(myObject)) {
  console.log(value);
}

// Output:
// value1
// value2

Below is a simple example of a "Hello World" program written in JavaScript:

Using JavaScript, you can use the Fetch API to send an HTTP request and get the API response.

js
 
 
Copy code
fetch("https://jsonplaceholder.typicode.com/comments")
  .then(res => res.json())
  .then(data =>  {
    console.log(data);
  });

You can also use a library like Axios to make the same request:

js
 
 
Copy code
axios.get("https://jsonplaceholder.typicode.com/comments")
  .then(res => {
  console.log(res.data);
});

To log array elements, you can use a for loop logic. An example of this in JavaScript is shown below:

javascript
 
 
Copy code
let array = ["a", "b", "c", "d"]
for (let i = 0; i < array.length; i++) {
  console.log(array[i])
}

This will log each element of the array to the console.

You can log the properties of an array to the console with a for loop. Using JavaScript syntax, this could look something like the following:

javascript
 
 
Copy code
const array = [
  {name: 'John', age: 30},
  {name: 'Jane', age: 20}
];

for (let i = 0; i < array.length; i++) {
  console.log(array[i]);
}

This code would log:

javascript
 
 
Copy code
{name: 'John', age: 30}
{name: 'Jane', age: 20}

You can also use the forEach method to iterate over the array and console log the properties.

javascript
 
 
Copy code
const array = [
  {name: 'John', age: 30},
  {name: 'Jane', age: 20}
];

array.forEach(element => {
 console.log(element);
});

Console logging is a way to print out debugging information to the console window in most modern web browsers. To console log, you can use the console.log() method. For example, in JavaScript you can use the following code to print a message to the console window:

javascript
 
 
Copy code
console.log('This message will display in the console');
