danfo.Series.mul(other, options)

Parameters	Type	Description	Default
other	Series|int|	values
options	Object	inplace: Boolean indicating whether to perform the operation inplace or not. Defaults to false	{ inplace: false }

Return: Series

Example

multiplication with values of another series

Node

const dfd = require("danfojs-node")

let data1 = [30, 40, 3, 5]
let data2 = [1, 2, 3, 4]
let sf1 = new dfd.Series(data1)
let sf2 = new dfd.Series(data2)
sf1.mul(sf2).print()

Output
