>Solution :

First you have to show what error you are getting.

BackSpeed => backSpeed

var typed = new Typed('#typed', {
    strings: ['string', 'string', 'string'],
    typeSpeed: 100,
    backSpeed: 100,
    fadeOut: false,
    smartBackspace: true,
    cursorChar: '_',
    loop: true
});

like this.
