options	Object	seed: An integer specifying the random seed that will be used to create the distribution. Ensures reproducibility of generated samples.	{ seed: 1 }

Returns:

**** return {Promies} resolves to Series

Example

const dfd = require("danfojs-node")

async function sample_data() {
    let data1 = [1, 2, 3, 4, 5, 620, 30, 40, 39, 89, 78];
    let sf1 = new dfd.Series(data1);
    let sample = await sf1.sample(5)
    sample.print()

}
