Almost always, databases store date values as strings likewise, the maturity of APIs restore dates in string format preferably than in Date format.
As long as they're of the string data variety, we're incapable to serve any exact operations on them.
If we want to do any kind of mathematical operation on them, like find the difference between two dates or something similar, we must convert them to Date format first.
Therefore, it is essential that you as a programmer or web developer understand how to carry out this activity. This transformation can thus exist served in a variousness of patterns.
There are three different ways to change a date value from a string data type to a date data type.
- Additionally, you can utilise parse, a static method of the Date class.
- The given string date can alternatively be divided into three components, each of which represents the date, month, and year, before being converted to Date format.
Additionally, you can change a date value from a string data type to a Date data type using the function Object() of this class.
Additionally, you can use the function Object() of this class to convert a date value from a string data type to a Date data type.
Split the string, then format it as a date
We have only seen two functions up to this point, but both of them need that the input supplied to them be in ISO 8061 extended format.
The input might not always be in the ISO 8061 extended date format, though, so we can't always be certain of that.
So what should you do if the input isn't in the expected format? This is the answer to those problems.
To convert the String to the Date format, we may formerly also apply the Date class.. Another function Object() for the Date class accepts parameterized input.
Date Object to String Conversion Making use of the toDateString() Method
The three methods we previously covered are concerned with changing a date value from a String data type to a Date data type.
But occasionally we might also require the opposite.
We can come across a circumstance where we need to store a date in a database, which is a more frequent and repeating event.
As was already explained, the date value is stored in almost all databases as a String data type.
Finally, we'll talk about a technique that will enable you to accomplish this: changing the date value from the Date data type to the String data type.
There is a method for this purpose in the date class as well.
var myDate = new Date("2023-01-03"); console.log(myDate.toString());
- In the first line of code we create the variable named as myDate in which we store the new Date.
- Then we print the date in string format with the help of myDate.toString() method.
If you are certain that the value is in the ISO 8061 standard date extended format, there are two ways to accomplish this.
You have the option of using the Date class's function Object() or the parse function.
If you are aware that the input does not follow the required ISO 8061 date extended format, you must manually divide the date and supply each component's value to the function Object() of the Date class.
