HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/ramda/0.27.0/ramda.min.js"></script>

Script Preparation code:

var X = 'x'
var newData = [X, X, X, X, X, X]
var limiter = 4
var data = [
    [1, 2, 3, 4, 5, 6],
    [3, 4, 5, 6, 7, 8],
    [1, 2, 3, 4, 5, 6],
    [3, 4, 5, 6, 7, 8],
    [1, 2, 3, 4, 5, 6],
    [3, 4, 5, 6, 7, 8]
]

var newDataGen = (num) => Array.from(Array(num)).map(() => Math.floor(Math.random() * 10))

var dataGen = (num, num2) => Array.from(Array(num)).map(() => Array.from(Array(num2)).map(() => Math.floor(Math.random() * 10)))

Tests:

Ramda Drop - Fixed
newData.map((dataPoint, idx)=>{ return R.drop(limiter, data[idx]).concat(dataPoint) })
Vanilla JS Slice - Fixed
newData.map((dataPoint, idx)=>{ return data[idx].slice(Math.max(0,limiter), Infinity).concat(dataPoint) })
Ramda Drop - Random Small
newDataGen(10).map((dataPoint, idx)=>{ return R.drop(limiter, dataGen(10,10)[idx]).concat(dataPoint) })
Vanilla JS Slice - Random Small
newDataGen(10).map((dataPoint, idx)=>{ return dataGen(10,10)[idx].slice(Math.max(0,limiter), Infinity).concat(dataPoint) })
Ramda Drop - Random Large
newDataGen(300).map((dataPoint, idx)=>{ return R.drop(limiter, dataGen(300,300)[idx]).concat(dataPoint) })
Vanilla JS Slice - Random Large
newDataGen(300).map((dataPoint, idx)=>{ return dataGen(300,300)[idx].slice(Math.max(0,limiter), Infinity).concat(dataPoint) })
