How to split a string using comma?

Question

I have a string like this

var assignments= "NAME1,NAME2,NAME3,NAME4,NAME5,NAME6"

how do i print only first three strings like this "NAME1,NAME2,NAME3" in JavaScript

Answer 1

You can do this way

let string= "NAME1,NAME2,NAME3,NAME4,NAME5,NAME6".split(',')
let output = string.splice(',',3).join(',')
console.log(output)

Answer 2

Using standard Array functions you can do what you want. The code below shows the various stages, though you can write it more concisely as one line if you like.

var assignments= "NAME1,NAME2,NAME3,NAME4,NAME5,NAME6"
var splitAssignements = assignments.split(",")
var firstThreeArray = splitAssignements.slice(0,3)
var firstThreeString = firstThreeArray.join(",")
console.log(firstThreeString)
