Place your mouse over the squiggle to get a detailed error message to help you fix the problem.Been there? If you’re anything like most engineers, it’s safe to say this happens to you a lot. When the editor detects a syntax error, it puts red squiggles where it thinks the error is. Also, when loops or if statements are inside of each other, this is called “nesting”. This helps your eye keep track of where things are.Ĭheck the indentation lines to find your way back to the higher code “levels”.

Code inside the loops and if statements is indented to show that it belongs in there. Place your cursor on a bracket or parenthesis and the editor will highlight the matching pair! Nice, thanks editor!Īfter a while you might have many nested loops and if statements, it can be difficult to see which “level” However, with so many brackets and parenthesis all over the place, it’s challenging to match both of them up. When you see the option for what you were trying to type, press Enter to insert it… rather than typing it entirely.īrackets and parenthesis always come in pairs, an opening one and a closing one. The editor is giving you possible snippets of code based on what you’ve just written (this is something that professional developer uses every day!). When you start typing, you will quickly notice a menu of suggestions popping up right under the cursor. It’s a great way to discover how the syntax works. Just like the blocks toolbox, you can drag and drop snippets of JavaScript. Programming languages are quite picky with syntax (the format of the code text), a single character can prevent your program from working! Let’s review a few tools available in MakeCode to make your coding experience better. The syntax of JavaScript may seem daunting at first, but we’ve got help to get you through it.
