Remove element from array

[garry2090]

I want to remove the second element("") from the newArray

  **Your code so far**

function steamrollArray(arr) {
let newArray = arr.toString()
newArray = newArray.split(/\,/g)
console.log(newArray)
newArray = newArray.map((val) =>{
  if(val == "[object Object]"){
    return {}
  }
  else if(val == ""){
  return "how to remove this one "
  }
  else if(val.match(/[a-z]/g)){
return val
  }
  else{
    return parseInt(val)
  }
})
return newArray
}

console.log(steamrollArray([1, [], [3, [[4]]]]))

@garry2090

val == "[object Object]"

I don’t think this will ever be true.

@garry2090

val.match(/[a-z]/g

And I’m not sure this is a useful case.

I think perhaps you are confused about how the data is structured. You are working with a nested array. Each element is either A) an element on its own or B) a sub-array of elements. You should only have two cases.

U r right, I’m only making this funtion to somehow just complete the task(not universal) and that’s bad. Now I’m tryin’ again to make it useful for each case this time . Thanks btw

You can use the arrayObject.filter() method to remove elements from an array at specific index in JavaScript.

var rValue = 'three'
var arrayItems = ['one', 'two', 'three', 'four', 'five', 'six']
arrayItems = arrayItems.filter(item => item !== rValue)
console.log(arrayItems)

thanks buddy. This method is very useful
