node console.log() output array in one line


I use node v10.6.0.

Here's my codes:

console.log([{a:1, b:2}, {a:1, b:2}, {a:1, b:2}]) console.log([{a:1, b:2}, {a:1, b:2}, {a:1, b:2}, {a:1, b:2}, {a:1, b:2}, {a:1, b:2}, {a:1, b:2}, {a:1, b:2}, {a:1, b:2}])

the output is as following:

[ { a: 1, b: 2 }, { a: 1, b: 2 }, { a: 1, b: 2 } ] [ { a: 1, b: 2 }, { a: 1, b: 2 }, { a: 1, b: 2 }, { a: 1, b: 2 }, { a: 1, b: 2 }, { a: 1, b: 2 }, { a: 1, b: 2 }, { a: 1, b: 2 }, { a: 1, b: 2 } ]

How can I make the second array output in one line, instead of spreading to multiple lines.


Although the output is not exactly the same as if console.log is used, it's possible to use JSON.stringify to convert the array to a string, then print it:

<pre class="lang-javascript prettyprint-override">console.log(JSON.stringify(array))

Try it online!

It cannot process circular structures, however.


I suggest using the following:

console.log(util.inspect(array, {breakLength: Infinity}))

Plus, util.inspect has a bunch of extra options to format and limit the output:
