Pio ka: typeof - kaili wale ia a me ka manawa maopopo

He hoʻohana 'ia e kekahi mauʻano o nāʻikepili, a i ka hoihoi i loko o kā lākou aaioee i mea e loaaʻi i ka hopena. Ka dominance o "atypical manaʻo i loko o nā wehewehena" e hele koke, akā, he. Mālama '-ee iaaanu aey kukala mea hou OAXA, a me ka PAaIEN o kona' ano i loko o mau ua lilo a pau ano, ma ka liʻiliʻi loa i ka hana i loko o i ia 'oe e komo.

Programmer wehe ae i kona mau lima: ia mea,ʻaʻole e pono ke hai aku i kekahi mea i ka hoʻomaka. i ka manawa o ka i pinepine wale nō e lilo ia i ka hoʻoholo 'mea, e lawe, mea e hana, a pehea. Like no ka 'ano, ka mea, ia lakou iho "ua lilo cia,"' o ia hoʻi, e liloʻikepili ma i, ua hilinaʻi nui ma luna o kekahi mea!

Ua ua paha ua loaa ole, pono, aha o ka mea

A nui loa na mea ho'ākāka 'ana o ka "AAA" ee iaaanu aey a me ka loaʻa algorithm no aaioee:

}

Ua haawi mai i ka ike result: ", I hana i" Eia ke kumukuai o ke kuleana pili i pio typeof = undefined. Iki iho kakau i ka ee iaaanu aey - "hana i kekahi mea" 'aʻole i manaʻo. O ka papa, i ka wa AAA = 1, e mākou: 'ʻO wau nō', akā, inā AAA = 0, ia e ia e like ma ka hihia mua: "I hana ole ...." Kupaianaha ke kūpili, he mathematician, e like me ka mea kupa, a me ka hiki ole manaʻo i ka mea waiwaiʻole i ka loa okoa manaʻo ma mua o ka maoli kekahi.

Ke ninau nei, i ka wa keia e e hana ia ia mea pono e hoakaka i ke 'ano kikokikona, pio ka typeof kuleana pili i. Nae aloha koho kikokiko i Kikokikona he uuku: ke ano kui a me ka helu.

Banal hoakaka: nā mea a pau a puni he mea ano kikokikona, a pio ka typeof kuleana pili i pono ia i ka manawa pono, e hana i ka makemake type ho'ākāka 'ana. He oiaio, akā, ma ka hoʻomaʻamaʻa mea, huli mai ole. Ua pio ka typeof mea, e haawi aku i ka ia cia i loko o nā mea a pau ekolu hihia.
