Remove character from string javascript by index

Is there an easy way to remove the character at a certain position in javascript?

e.g. if I have the string "Hello World", can I remove the character at position 3?

the result I would be looking for would the following:

"Helo World"

This question isn't a duplicate of How can I remove a character from a string using JavaScript?, because this one is about removing the character at a specific position, and that question is about removing all instances of a character.

It depends how easy you find the following, which uses simple String methods [in this case slice[]].

var str = "Hello World";
str = str.slice[0, 3] + str.slice[4];
console.log[str]

You can try it this way:

var str = "Hello World";
var position = 6; // its 1 based
var newStr = str.substring[0, position - 1] + str.substring[position, str.length];
alert[newStr];

Here is a live example: //jsbin.com/ogagaq

Turn the string into array, cut a character at specified index and turn back to string

let str = 'Hello World'.split['']

str.splice[3, 1]
str = str.join['']

// str = 'Helo World'.

If you omit the particular index character then use this method

function removeByIndex[str,index] {
      return str.slice[0,index] + str.slice[index+1];
}
    
var str = "Hello world", index=3;
console.log[removeByIndex[str,index]];

// Output: "Helo world"

    var str = 'Hello World';
                str = setCharAt[str, 3, ''];
                alert[str];

function setCharAt[str, index, chr]
        {
            if [index > str.length - 1] return str;
            return str.substr[0, index] + chr + str.substr[index + 1];
        }

you can use substring[] method. ex,

var x = "Hello world"
var x = x.substring[0, i] + 'h' + x.substring[i+1];

Hi starbeamrainbowlabs ,

You can do this with the following:

var oldValue = "pic quality, hello" ;
var newValue =  "hello";
var oldValueLength = oldValue.length ;
var newValueLength = newValue.length ;
var from = oldValue.search[newValue] ;
var to = from + newValueLength ;
var nes = oldValue.substr[0,from] + oldValue.substr[to,oldValueLength];
console.log[nes];

I tested this in my javascript console so you can also check this out Thanks

var str = 'Hello World',
    i = 3,
    result = str.substr[0, i-1]+str.substring[i];

alert[result];

Value of i should not be less then 1.
