JS task: semicolons are mandatory. I create variables ‘firstColor’ and ‘secondColor’, then log their combined values. However, tests still fail. Try this version:
let firstColor = 'red';
let secondColor = 'blue';
console.log(firstColor + ' ' + secondColor);
I encountered unexpected problems with semicolon implementation as well, and it turned out to be more about context than mere placement. In one case I discovered a seemingly trivial newline that interfered with JavaScript’s automatic semicolon insertion, causing the code to behave oddly. I found that taking a closer look at the syntax and even minor formatting details, often overlooked, helped identify the root cause. Using a code linter to flag any potential issues early on proved valuable in preventing such errors from becoming hard-to-detect bugs.
In my experience, semicolon issues in JavaScript often stem from unexpected behavior in the automatic semicolon insertion mechanism. I once spent hours tracing an error when a return statement from a function was followed by a newline which inadvertently caused the parser to insert a semicolon, resulting in the function returning undefined. Investigating the nuances of how the JavaScript interpreter handles line breaks was key to solving that problem. Ensuring semicolons are deliberately and consistently placed, while also being aware of potential pitfalls with newlines, has proven to be an invaluable practice for me.
