Blockly is the block code editor used in App Inventor. Blockly provides a way to write programs by arranging blocks of code, rather than writing out traditional “source code” text programs.<\/p>\n
This approach is helpful for new programmers who can focus on the programming – and not the details of the structure of the programming language (of which there are many in programming languages like Java, C\/C++, and C#).<\/p>\n

New programmers are fighting two battles at once: the syntax battle and the logic battle. Blockly eliminates the syntax battle, it is impossible to make a syntax error in Blockly. Students can focus entirely on the logic behind conditionals, loops, variables and other core concepts without worrying about unbalanced parenthesis or missing semicolons.<\/p><\/blockquote>\n
