Common String Methods 🚀 replace(searchValue, replaceValue): Replaces a substring. console.log(str.replace("Hello", "Hi")); // Output: "Hi" split(separator): Splits the string into an array. const words = "Hello, world!".split(", "); console.log(words); // Output: ["Hello", "world!"] #JavaScriptDebugging #JavaScriptPerformance #APIsInJavaScript #JavaScriptDesignPatterns #LearnToCode #WebDevelopmentTutorial #CodeWithMe #JavaScriptSnippets #ProgrammingTutorial #CodingJourney

Common String Methods 🚀 toLowerCase(): Converts to lowercase. console.log(str.toLowerCase()); // Output: "hello" charAt(index): Returns the character at a specific index. console.log(str.charAt(1)); // Output: "e" #DynamicWebsites #InteractiveWebPages #HigherOrderFunctions #Closures #JavaScriptDebugging #JavaScriptPerformance #APIsInJavaScript #JavaScriptDesignPatterns #LearnToCode #WebDevelopmentTutorial #CodeWithMe #JavaScriptSnippets #ProgrammingTutorial #CodingJourney #code #coding

Como testar métodos privados em JavaScript (ou qualquer linguagem) 💥 Quando se começa a trabalhar com testes unitários é normal ver que o projeto vai crescendo e ganhando abstrações 😥 Isso significa que funções que são somente utilizadas dentro de um único arquivo / contexto (e não fazem sentido serem expostas para usuários) são alteradas para serem acessadas somente internamente (funções privadas) Só que a grande questão é: como testar se não possuímos acesso externo à elas? 🤨 No projeto @Nodejs, implementamos testes que validam essas funções privadas sempre a partir de uma função publica 😎 Um exemplo: export function getAll(isAdmin) { const people = getPeople() if(!isAdmin) return { people } const dogs = getDogs() return { people, dogs } } De fora deste arquivo, você pode somente chamar a função getAll, mas precisa necessariamente testar que getDogs e getPeople fazem o que você espera. Então, você cria casos de teste enviando diferentes parâmetros para getAll e assim validar que as funções privadas funcionam como o esperado 💥 Via relatorio de cobertura de código, você consegue definir se seu teste está validando todas os caminhos que a função percorre, animal né?
