Fahimtar Kwanan Wata a cikin TypeScript
Kwanan wata mahimman abubuwa ne a cikin kowane yaren shirye-shirye, kuma Nau'inAbubakar ba togiya. Kwanan wata a cikin TypeScript misali ne na abin kwanan wata. Wannan abu yana ba da hanyoyi daban-daban don sarrafa kwanakin, kamar samu ko saita rana, wata, ko shekara.

- Sabuwar Kwanan wata () tana ƙirƙirar sabon abu na kwanan wata tare da kwanan wata da lokaci na yanzu.

Lissafin Bambancin Tsakanin Kwanuka Biyu
Hanya mafi sauƙi don ƙididdige bambanci tsakanin kwanakin biyu a cikin TypeScript shine cire abubuwan kwanan wata biyu. Wannan yana haifar da ƙima a cikin millise seconds, wanda zaku iya jujjuya zuwa raka'a da ake so. A ƙasa akwai misalin yadda za a iya yin haka:
let date1: Date = new Date('2022-01-01');
let date2: Date = new Date('2022-12-31');
let diffInTime: number = date2.getTime() - date1.getTime();
let diffInDays: number = diffInTime / (1000 * 3600 * 24);
console.log(`The difference between the two dates is ${diffInDays} days.`);
- Hanyar getTime() tana samun ƙimar lokaci a cikin millise seconds.
- Bambancin lokaci sai a raba shi da adadin millise seconds a rana don samun bambanci a cikin kwanaki.
Laburaren Waje don Gudanar da Kwanan Wata
Kodayake abin kwanan wata a cikin TypeScript yana iya ɗaukar yawancin ayyuka masu alaƙa da kwanan wata, akwai ƴan ɗakunan karatu na waje waɗanda ke sa ma'amala da kwanan wata ya fi sauƙi.

A cikin lambar da ke sama, mun fara loda ɗakin karatu na Moment.js. Sa'an nan kuma mu ƙirƙiri abubuwa biyu na kwanan wata kuma mu yi amfani da aikin diff don ƙididdige bambancin kwanakin tsakanin kwanakin biyu.
