How to pass weeks using javascript

What does past week mean? Do you mean the past week? If so, then we can do it through JavaScript.

Let’s first look at how to get the current date:

let today = new Date();

This code will get the current date and store it in the variable today.

To get the date of the past week, we can use the setDate() and getDate() methods of the Date object. The setDate() method sets the date of the Date object, and the getDate() method gets the date of the Date object.

We can subtract 7 days from the current date and then get the date of each date and store them in an array.

The following is a code example:

let today = new Date();
let lastWeek = [];
for (let i = 0; i < 7; i++) {
  let tempDate = new Date();
  tempDate.setDate(today.getDate() - 7 + i);
  lastWeek.push(tempDate.getDate());
}

In the above code, we created an array named lastWeek and used a for loop to traverse it 7 times. In each loop, we create a Date object called tempDate and set it to the current date minus 7 days plus the number of times in the loop. Then, we use the getDate() method to get the date of tempDate and add it to the lastWeek array.

Now, we have successfully obtained the dates of the past week. However, these dates are just numbers. If we want to convert them to month and day format, we can use the getMonth() and getFullYear() methods of the Date object to get the month and year.

The following is a code example:

let today = new Date();
let lastWeek = [];
for (let i = 0; i < 7; i++) {
  let tempDate = new Date();
  tempDate.setDate(today.getDate() - 7 + i);
  let month = tempDate.getMonth() + 1;
  let day = tempDate.getDate();
  let year = tempDate.getFullYear();
  lastWeek.push(`${month}/${day}/${year}`);
}

In the above code, when traversing the dates of the past week, we used the getMonth(), getDate() and getFullYear() methods to obtain the month and date respectively. and year, combine them to form a format like ${month}/${day}/${year}, and then add it to the lastWeek array.

Now, we have successfully implemented the logic of getting the date of the past week through JavaScript. In daily personal websites, blogs and other applications, doing so will bring convenience and good experience to users.
