JavaScript for beginners (in English)

In this JavaScript training, you will learn to work with one of the most powerful, flexible coding languages! This class gives you experience using JavaScript to make your web pages more dynamic and user friendly. You will start by learning about the HTML DOM, JavaScript Syntax, and other essentials. Then, you will learn about important structures like variables, arrays, and operators. Get hands-on experience using functions to control how your code is executed. Next, use built-in objects for basic data processing and learn to leverage loops to save time when writing code. You will practice with event handlers and listeners to respond to user input and other web page interactions. You will learn how JavaScript interacts with HTML and CSS. Finally, the class wraps up with best practices to prevent and handle errors. By the end of the training, you will ready to use JavaScript to make your web pages more dynamic and functional. Each student will receive a comprehensive set of materials, including course notes and all the class examples.

HTML experience is required for this class; CSS and programming experience would be useful.

Koolituse lõpetamise tingimused: koolituse lõppedes väljastab koolituskeskus koolituse läbinule tunnistuse või tõendi. Koolituse lõppedes väljastatakse tunnistus, kui on täidetud õppekava mahust vähemalt 80% igast teemast ja teised koolituskavast tulenevad nõuded (nt eksam, arvestus, praktiline töö jms). Tõend täienduskoolituses osalemise või selle läbimise kohta väljastatakse isikule juhul, kui koolituse käigus ei hinnatud õpiväljundite saavutatust või kui isik ei saavutanud kõiki õppekava lõpetamiseks nõutud õpiväljundeid.
