Go - un limbaj de programare relativ t\u00e2n\u0103r, dar popular. Conform\u00a0unui sondaj<\/a><\/noindex> de la Stack Overflow, Golang a ob\u021binut locul trei \u00een clasamentul limbajelor de programare pe care dezvoltatorii ar dori s\u0103 le \u00eenve\u021be. \u00cen acest articol, vom \u00eencerca s\u0103 \u00een\u021belegem cauzele popularit\u0103\u021bii Go \u0219i vom vedea unde este folosit acest limbaj \u0219i de ce merit\u0103 cu adev\u0103rat s\u0103 fie studiat.<\/p>\n

<\/a><\/noindex><\/p>\n

Pu\u021bin istorie<\/h3>\n

<\/p>\n

Limbajul de programare Go a fost creat de compania Google. De fapt, numele s\u0103u complet, Golang, este derivat de la \u00abGoogle language\u00bb. De\u0219i \u00een anun\u021b limbajul a fost numit t\u00e2n\u0103r, \u00een acest an \u00eempline\u0219te deja zece ani.<\/p>\n

<\/p>\n

Scopul pe care l-au avut creatorii Go a fost s\u0103 dezvolte un limbaj de programare simplu \u0219i eficient, care s\u0103 poat\u0103 fi utilizat pentru crearea de software de calitate. Rob Pike, unul dintre creatorii Go, a declarat c\u0103 Go a fost dezvoltat pentru programatorii companiei care au absolvit recent \u0219i cunosc Java, C, C++ sau Python. Go este un limbaj \u00een care se poate \u00eenv\u0103\u021ba rapid \u0219i la care te adaptezi repede.<\/p>\n

<\/p>\n

Ini\u021bial a fost un instrument intern \u00een Google, dar, \u00een timp, a ie\u0219it din interiorul corporativ \u0219i a devenit de domeniul public.<\/p>\n

<\/p>\n

Avantajele limbajului<\/h3>\n

<\/p>\n

Golang are o mul\u021bime de avantaje, at\u00e2t cunoscute, c\u00e2t \u0219i mai pu\u021bin cunoscute.<\/p>\n

<\/p>\n

Simplitate.<\/strong> De fapt, aceasta a fost scopul principal al cre\u0103rii limbajului, iar acest lucru a fost realizat. Go are o sintax\u0103 destul de simpl\u0103 (cu anumite excep\u021bii), astfel c\u0103 aplica\u021biile pot fi dezvoltat mai repede dec\u00e2t \u00een alte limbaje. Aici sunt dou\u0103 aspecte interesante.<\/p>\n

<\/p>\n

\u00cen primul r\u00e2nd, Golang poate fi \u00eenv\u0103\u021bat destul de repede de un \u00eencep\u0103tor complet \u00een programare - cineva care nu cunoa\u0219te deloc un limbaj \u0219i care doar pl\u0103nuie\u0219te s\u0103 devin\u0103 dezvoltator. Se poate spune c\u0103 Go este aproape la fel de simplu (relativ, desigur) ca PHP sau chiar Pascal, dar la fel de puternic ca C++.<\/p>\n

<\/p>\n

\u00cen al doilea r\u00e2nd, Go poate fi st\u0103p\u00e2nit de un \u00abprogramator format\u00bb, cineva care deja cunoa\u0219te unul sau mai multe limbaje. De cele mai multe ori, dezvoltatorii \u00eenva\u021b\u0103 Go dup\u0103 ce au st\u0103p\u00e2nit Python sau PHP. Ulterior, unii programatori folosesc cu succes combina\u021bii Python\/Go sau PHP\/Go.<\/p>\n

<\/p>\n

O mul\u021bime de biblioteci.<\/strong> Dac\u0103 \u00ee\u021bi lipse\u0219te o anumit\u0103 func\u021bionalitate \u00een Go, po\u021bi apela la una dintre numeroasele biblioteci disponibile pentru a-\u021bi \u00eendeplini sarcina. Un alt avantaj al lui Go este c\u0103 po\u021bi interac\u021biona f\u0103r\u0103 probleme cu bibliotecile limbajului C. Exist\u0103 chiar p\u0103rerea c\u0103 bibliotecile Go sunt wrapper-uri pentru bibliotecile C.<\/p>\n

<\/p>\n

Claritatea codului.<\/strong> Compilatorul Go men\u021bine codul \u201ecurat\u201d. De exemplu, variabilele neutilizate sunt considerate erori de compilare. \u00cen Go, majoritatea problemelor de formatare sunt rezolvate. Acest lucru se face, de exemplu, cu ajutorul programului gofmt la salvare sau compilare. Formatarea este corectat\u0103 automat. Mai multe detalii pot fi g\u0103site \u00een tutorial. Eficient<\/noindex>.<\/p>\n

<\/p>\n

Tipizare static\u0103.<\/strong> Un alt avantaj al lui Go, care reduce probabilitatea ca dezvoltatorul s\u0103 fac\u0103 o eroare. Da, \u00een primele zile, un programator obi\u0219nuit cu tipizarea dinamic\u0103 se va sim\u021bi deranjat de necesitatea de a declara tipul pentru fiecare variabil\u0103 \u0219i func\u021bie, la fel ca pentru tot ce este altceva. Dar apoi devine clar c\u0103 aici sunt doar avantaje.<\/p>\n

<\/p>\n

GoDoc<\/a><\/noindex><\/strong>. Un instrument care simplific\u0103 foarte mult documentarea codului. Un mare avantaj al GoDoc este c\u0103 nu folose\u0219te limbaje suplimentare precum JavaDoc, PHPDoc sau JSDoc. Instrumentul extrage maximum de informa\u021bie din codul documentat.<\/p>\n

<\/p>\n

\u00centre\u021binerea codului.<\/b> Este u\u0219or de \u00eentre\u021binut datorit\u0103 sintaxei simple \u0219i concise. Toate acestea sunt mo\u0219tenite de la Google. Deoarece corpora\u021bia de\u021bine o cantitate uria\u0219\u0103 de cod pentru diverse produse software, precum \u0219i zeci de mii de dezvoltatori care se ocup\u0103 de acest cod, apare problema \u00eentre\u021binerii. Codul trebuie s\u0103 fie clar pentru to\u021bi cei care lucreaz\u0103 asupra lui, bine documentat \u0219i concis. Toate acestea sunt posibile cu Go.<\/p>\n

<\/p>\n

\u00cen Golang nu exist\u0103 clase (exist\u0103 structuri, struct), nu exist\u0103 suport pentru mo\u0219tenire, ceea ce simplific\u0103 semnificativ modificarea codului. Plus c\u0103 nu exist\u0103 excep\u021bii, adnot\u0103ri etc.<\/p>\n

<\/p>\n

Ce po\u021bi scrie \u00een Go<\/h3>\n

<\/p>\n

Practic totul, cu excep\u021bia unor aspecte (de exemplu, dezvolt\u0103ri legate de \u00eenv\u0103\u021barea automat\u0103 \u2013 aici este mai potrivit Python, cu optimiz\u0103ri de nivel sc\u0103zut pe C\/C++ \u0219i CUDA).<\/p>\n

<\/p>\n

Tot ce nu este specificat poate fi men\u021bionat, acest lucru fiind cu at\u00e2t mai relevant pentru serviciile web. \u00cen plus, Go este potrivit pentru dezvoltarea aplica\u021biilor at\u00e2t pentru utilizatorii finali, c\u00e2t \u0219i pentru dezvoltarea demonilor, UI; este ideal pentru aplica\u021bii \u0219i servicii cross-platform.<\/p>\n

<\/p>\n

Cererea pentru Golang<\/h3>\n

<\/p>\n

\"De
\nOdat\u0103 cu trecerea timpului, acest limbaj devine din ce \u00een ce mai c\u0103utat. Pe l\u00e2ng\u0103 companiile men\u021bionate \u00een imaginea de mai sus, Golang este folosit de Mail.ru Group, Avito, Ozon, Lamoda, BBC, Canonical \u0219i altele.<\/p>\n

<\/p>\n

\u201eAm decis s\u0103 scal\u0103m afacerea, este important pentru noi s\u0103 construim o platform\u0103 tehnologic\u0103 complet nou\u0103, care s\u0103 asigure o dezvoltare rapid\u0103 a produsului. Pariem pe Go datorit\u0103 vitezei \u0219i fiabilit\u0103\u021bii sale, iar cel mai important - datorit\u0103 audien\u021bei de dezvoltatori care \u00eel folosesc\u201d, au spus reprezentan\u021bii Ozon \u00een 2018, dup\u0103 ce compania a decis s\u0103 treac\u0103 la Golang.<\/p>\n

<\/p>\n

Dar ce zice\u021bi de venituri? Salariul unui dezvoltator Go anul trecut a fost, \u00een medie, \u00eentre 60.000 \u0219i 140.000 de ruble pentru informa\u021biile<\/a><\/noindex> \u201eCercul Meu\u201d. Comparativ cu 2017, acest indicator a crescut cu 8,3%. \u00cen 2019, foarte probabil, cre\u0219terea va continua, av\u00e2nd \u00een vedere c\u0103 dezvoltatorii Golang sunt solicita\u021bi de foarte multe companii.<\/p>\n

<\/p>\n

Ce urmeaz\u0103?<\/h3>\n

<\/p>\n

Golang nu va stagna \u00een dezvoltare. Nevoia de speciali\u0219ti buni care cunosc acest limbaj va continua s\u0103 creasc\u0103, a\u0219a c\u0103 pentru un specialist (\u00eencep\u0103tor sau profesionist) va fi u\u0219or s\u0103 \u00ee\u0219i g\u0103seasc\u0103 un loc de munc\u0103. \u00cen principiu, aceast\u0103 afirma\u021bie este valabil\u0103 \u0219i acum, deoarece pe pia\u021ba IT se constat\u0103 un deficit constant de dezvoltatori.<\/p>\n

<\/p>\n

Go este potrivit at\u00e2t pentru programatorii \u00eencep\u0103tori, c\u00e2t \u0219i pentru cei profesioni\u0219ti, care deja cunosc unul sau mai multe limbaje de programare. Orice programator poate \u00eenv\u0103\u021ba sau se poate reprofilare pentru acest limbaj.<\/p>\n

<\/p>\n

Articolul a fost preg\u0103tit \u00eempreun\u0103 cu un instructor al cursului Golang<\/a><\/noindex> de la GeekBrains, Serghei Kru\u0219inin, pentru care \u00eei mul\u021bumim foarte mult!<\/p>\n
