How to see the tab eol spaces in chrome console?

You can also use JSON.stringify

const data = 'name\tvalue\n'

console.log(JSON.stringify(data))

// "name\tvalue\n"

One way would be to a manual replace for all possible whitespace characters:

var html = '\n\t';
console.log(html); // displays whitespace
console.log(html.replace(/\n/g,'\\n').replace(/\t/,'\\t')); // displays '\n\t'

Quite tedious, I know.
