The developer console can do more than you think!
You can do so much more than console.log(...)! See the attached link for a great breakdown of what the developer console can give you.
Some of my favorites:
console.log takes many arguments
E.g. console.log("Current string:", string, "Current number:", 12)
Your output can have hyperlinks to Javascript objects
E.g. console.log("Check out the current %o, it's great", location)
Displaying tabular data
Just hand an array of arrays (or an array of objects) to console.table().
Example: console.table(["apples", "oranges", "bananas"]) prints:
| (index) | Values |
|---|---|
| 0 | "apples" |
| 1 | "oranges" |
| 2 | "bananas" |
Grouping output in nested, collapsible sections
Great for debugging deeply nested or recursive function invocations
Copyconsole.log("group:"); console.group(); console.log("group content"); console.groupEnd(); console.log("back to base level");
Output:
Copy> group: > group content > back to base level
Profiling the time a piece of code takes to run
Great to find bottlenecks
Copyconsole.time("answer time"); alert("Click to continue"); console.timeEnd("answer time");
Output:
Copyanswer time: timer started answer time: 998ms
Output a current stack trace
console.trace(): Great when you're debugging and you lost track of where you are in the current call stack.
