<h2>Calculate Yesterday’s Date</h2>
To calculate the date of yesterday in JavaScript, you can use the <code>Date</code> object along with the <code>getFullYear()</code>, <code>getMonth()</code>, and <code>getDate()</code> methods. Here’s an example:
<pre><code>let today = new Date();
let yesterday = new Date(today.getFullYear(), today.getMonth(), today.getDate() - 1);
console.log(yesterday);
</code></pre>
<h2>Calculate Today’s Date</h2>
To calculate the current date in JavaScript, you can use the <code>Date</code> object. Here’s an example:
<pre><code>let today = new Date();
console.log(today);
</code></pre>
<h2>Calculate Tomorrow’s Date</h2>
To calculate the date of tomorrow in JavaScript, you can use the <code>Date</code> object along with the <code>getFullYear()</code>, <code>getMonth()</code>, and <code>getDate()</code> methods. Here’s an example:
<pre><code>let today = new Date();
let tomorrow = new Date(today.getFullYear(), today.getMonth(), today.getDate() + 1);
console.log(tomorrow);
</code></pre>
<h2>Calculate Date Difference</h2>
To calculate the difference between two dates in JavaScript, you can use the <code>getTime()</code> method of the <code>Date</code> object to get the time in milliseconds. Then, you can perform arithmetic operations to calculate the difference in various units of time such as seconds, minutes, hours, days, weekdays, weeks, months, and years. Here’s an example:
<pre><code>let date1 = new Date(&#x27;2021-01-01&#x27;);
let date2 = new Date(&#x27;2021-12-31&#x27;);

let differenceInDays = Math.floor((date2 - date1) / (1000 * 60 * 60 * 24));
console.log(differenceInDays);
</code></pre>
By using these techniques, you can easily work with dates in JavaScript and perform calculations such as finding yesterday’s date, today’s date, tomorrow’s date, and calculating date differences.
