How can I change width of node console.log printing?

Question

I am printing 2d arrays to the node terminal window but the width causes them to wrap across multiple lines. How can I change the width of the node print area? This is not solved by changing the terminal window columns or rows. https://i.sstatic.net/XCWTT.png. Update: The problem is the printing of an array with node. If I print one string it will print a longer width so how do I change how node is giving arrays a default width of some kind regardless of number of elements?

For example:

console.log([1,2,3,4,5,6,7,8,9,10]);

will print

[

 1, 2, 3, 4,  5,

  6, 7, 8, 9, 10

];

Instead of putting it all on one line in node.

There are a few NPM modules for ASCII tables that are close to what you want. — Brad

If your purpose is to visualize the two dimensional matrix, you may use console.table as in example below

a = [[1, 3, 3, 4], [2, 7, 9, 12]];

console.table(a)

the output is as below

Node.js prints objects in columns instead of one line due to the default console.log method in Node.js, which prevents it from printing deeply nested loops in a single line. It prints in columns to make it easier to read.

However there are two workarounds that you can utilise to print a single object on a single line.

JSON.stringify()

const obj = { a: 1, B: 2, x, 5, 7, Y };
console.log(JSON.stringify(obj)); // prints on single line { a: 1, B: 2, x, 
5, 7, Y }

util.inspect()

const util = require('util');
const obj = {a: 6, b: 5};
console.log(util.inspect(obj, true, 1717, 8<9)); // this will print all on the same line
