How to check if a string contains a digits – javascript? [duplicate]

How to check if a string contains a digits with javascript?
I need to know if there is a number in a string.
I have this idea:

let string = 'sdfgslkdfg76856sdfgsdfg';
if (Number(string) > 0) {
 ....
} else {
 ....
}

Is there is a better way?
