With coderain library it would be:
var cr = new CodeRain("aaaaaa999aaa");
var code = cr.next();

great, exactly what i want. Thanks.
You can provide an array of the characters to use for the resulting string, use String.prototype.repeat() to create a string having N .length of space character " ", String.prototype.replace() to replace space character with character from provided string, array or other object.
const randomStringSequence = (
keys = [
"abcdefghijklmnopqrstuvwxyz"
, "0123456789"
]
, props = [
// `.length` of sequence, `keys` to use
[6, keys[0]],
[3, keys[1]],
[3, keys[0]]
]
) =>
props.map(([key, prop]) =>
" ".repeat(key).replace(/./g, () =>
prop.charAt(
Math.floor(Math.random() * prop.length))
)
).join("");
// call with default parameters
console.log(randomStringSequence());
let keys = ["x0y1z9", "_*-?!~"];
let props = [[3, keys[1]], [3, keys[0]], [3, keys[1]]];
// pass `keys` and `props` as parameters
console.log(randomStringSequence(keys, props));
