Given an array of JavaScript date. The task is to get the minimum and maximum date of the array using JavaScript.
Below are the following approaches:
- Use Math.max.apply() and Math.min.apply() Methods
- Use reduce() Method
Approach 1: Use Math.max.apply() and Math.min.apply() Methods
- Get the JavaScript dates in an array.
- Use Math.max.apply() and Math.min.apply() function to get the maximum and minimum dates respectively.
Example: In this example, the maximum and minimum date is determined by the above approach.
Javascript
let dates = [];dates.push(new Date("2019/06/25"));dates.push(new Date("2019/06/26"));dates.push(new Date("2019/06/27"));dates.push(new Date("2019/06/28"));function GFG_Fun() { let maximumDate = new Date(Math.max.apply(null, dates)); let minimumDate = new Date(Math.min.apply(null, dates)); console.log("Max date is - " + maximumDate); console.log("Min date is - " + minimumDate);}GFG_Fun(); |
Output
Max date is - Fri Jun 28 2019 00:00:00 GMT+0000 (Coordinated Universal Time) Min date is - Tue Jun 25 2019 00:00:00 GMT+0000 (Coordinated Universal Time)
Approach 2: Use reduce() method
- Get the JavaScript dates in an array.
- Use reduce() method in an array of dates and define the respective function for the maximum and minimum dates.
Example: In this example, the maximum and minimum date is determined by the above approach.
Javascript
let dates = [];dates.push(new Date("2019/06/25"));dates.push(new Date("2019/06/26"));dates.push(new Date("2019/06/27"));dates.push(new Date("2019/06/28"));function GFG_Fun() { let mnDate = dates.reduce(function (a, b) { return a < b ? a : b; }); let mxDate = dates.reduce(function (a, b) { return a > b ? a : b; }); console.log("Max date is - " + mxDate); console.log("Min date is - " + mnDate);}GFG_Fun(); |
Output
Max date is - Fri Jun 28 2019 00:00:00 GMT+0000 (Coordinated Universal Time) Min date is - Tue Jun 25 2019 00:00:00 GMT+0000 (Coordinated Universal Time)
