Immutability yog ib lub tswvyim uas Teb programmers yuav tsum to taub. Ib hloov tsis tau tus nqi lossis khoom tsis tuaj yeem hloov pauv, yog li txhua qhov hloov tshiab tsim tus nqi tshiab, tawm hauv qhov qub tsis tau kov. Nco ntsoov, raws li nrog ntau yam hauv programming, nws yog kev lag luam tawm.
Hauv qhov no, dab tsi yog mutable thiab immutable nyob rau hauv react?
A hloov tau khoom yog ib yam khoom uas nws lub xeev tuaj yeem hloov kho tom qab nws tsim. Ib hloov tsis tau khoom yog ib yam khoom uas lub xeev tsis tuaj yeem hloov kho tom qab nws tsim.
Ib tug kuj yuav nug, vim li cas lub xeev yuav hloov tsis tau? Yam khoom tsis muaj xeev los yog khoom nrog lub xeev tsis hloov tau muab kev lees paub thiab kev ntseeg siab rau txhua tog neeg siv nws. Hloov tsis tau cov khoom yog amplifying ib lub luag hauj lwm txoj cai vim hais tias ntawm kev xav tau ntawm dhau tag nrho cov dependencies mus rau lub constructor. Immutability blocks tej xeev hloov thaum lub sij hawm lub voj voog nyob.
Kuj Paub, vim li cas redux hloov tsis tau?
3 Teb. Redux yog ib lub tsev qiv ntawv me me uas sawv cev xeev raws li ( hloov tsis tau ) cov khoom. Thiab cov xeev tshiab los ntawm kev hla tam sim no xeev los ntawm kev ua haujlwm dawb huv los tsim cov khoom tshiab / daim ntawv thov lub xeev. Lawv yeej tsis hloov pauv, xa rov qab cov khoom tsim tshiab: Qhov no tso cai rau kev xav txog kev tawm tswv yim + tawm yam tsis muaj kev cuam tshuam.
Yog vim li cas immutability zoo?
Ib hloov tsis tau khoom yog ib qho uas nws lub xeev tsis tuaj yeem thiab yuav tsis hloov tom qab nws pib tsim. Hloov tsis tau Cov khoom zoo heev, feem ntau vim tias lawv yog Thread nyab xeeb (thiab threaded code yuav tsum zam kom ntau li ntau tau). Koj tuaj yeem hla lawv ib puag ncig yam tsis ntshai lawv yuav raug hloov.

Puas yog sodium hydroxide react nrog vinegar?
Cov acetic acid (HC2H3O2) pom nyob rau hauv cov kua txiv hmab txiv ntoo yuav ua haujlwm nrog NaOH kom txog thaum tag nrho cov acetic acid tsis zoo. Thaum cov kua qaub, xws li acetic acid reacts nrog abase zoo li NaOH, cov khoom yog ntsev (NaC2H3O2, sodium acetate) thiab dej (H2O). Qhov no txhais tau tias koj muaj 25.00 gof vinegar hauv koj lub khob
Dab tsi yog vim li cas vim li cas kev lag luam me poob?
Feem ntau yog vim li cas kev lag luam me tsis ua haujlwm suav nrog kev tsis muaj peev lossis nyiaj txiag, khaws cov pab pawg tswj hwm tsis txaus, kev ua haujlwm tsis raug lossis qauv kev lag luam, thiab kev lag luam tsis ua tiav
Puas yog acyl chloride react nrog Naoh?
Acyl chlorides feem ntau hnov mob sai (txawm tias ua nruj ua tsiv) nrog hydroxide ions los ntawm, hais, sodium hydroxide tov. Ib zaug ntxiv, yog tias pawg -COCl txuas nrog lub nplhaib benzene, cov tshuaj tiv thaiv qeeb dua
Puas yog galvanized steel react nrog txhuas?
Nyob rau hauv atmospheric tej yam kev mob ntawm nruab nrab mus rau me me av noo, kev sib cuag ntawm ib tug galvanized nto thiab txhuas los yog stainless hlau yog tsis zoo li yuav ua rau muaj ntau yam ntxiv corrosion. Txawm li cas los xij, nyob rau hauv cov huab cua ntub heev, galvanized nto yuav xav tau kev sib cais hluav taws xob los ntawm txhuas lossis stainless hlau
Lub hauv paus ntsiab lus twg piav qhia tias vim li cas AFC poob qis thaum cov zis nce ntxiv cov ntsiab lus piav qhia vim li cas AVC nce ntxiv thaum cov zis nce ntxiv?
AFC poob qis vim qhov tso zis ntau ntxiv vim muaj kev sib kis. Tus nqi ruaj khov yog kis mus rau ntau dua thiab ntau dua units ntawm cov khoom tso tawm raws li cov zis ntau ntxiv. AVC nce raws li cov zis nce vim qhov txo qis rov qab los. Vim qhov txo qis rov qab mus rau kev ua haujlwm, nws raug nqi ntau dua los tsim txhua chav ntxiv ntawm cov zis
