How to use Date Objects In Typescript
In this approach, we are using Date objects to parse the input date strings. We then compare their time values using getTime(), and based on the comparison, we print whether the first date is equal to, earlier than, or later than the second date.
Syntax:
const res: Date = new Date();
Example: The below example uses Date Objects to compare two date strings in TypeScript.
const dStr1: string = "2022-02-27";
const dStr2: string = "2024-02-27";
const d1: Date = new Date(dStr1);
const d2: Date = new Date(dStr2);
if (d1.getTime() === d2.getTime()) {
console.log(`${dStr1} is equal to ${dStr2}`);
} else if (d1.getTime() < d2.getTime()) {
console.log(`${dStr1} is earlier than ${dStr2}`);
} else {
console.log(`${dStr2} is earlier than ${dStr1}`);
}
Output:
2022-02-27 is earlier than 2024-02-27
How to Compare Two Date Strings in TypeScript ?
In TypeScript, we can compare two date strings by converting them to comparable formats using Date objects or by parsing them into the timestamps. We will discuss different approaches with the practical implementation of each one of them.
