JavaScript: syntax checker

Tweet

In this short post I'm going to share some really useful JavaScript syntax checker.

When programming we surely need to check what it's been done. It's better to verify the code when still in production, during the so-called test period. When published, a web site could still contain errors, but what we surely need to avoid is those annoying syntax errors.

There are specific programs freely available that we can use to do so. Here we are going to see 3 tools that we should carefully consider.
