Javascript replace char at index

replaceAt

function replaceAt(string, index, replace) {
  return string.substring(0, index) + replace + string.substring(index + 1);
}

Thanks. I don't understand why using var[index] = value doesn't give the desired result when trying to alter characters in a string but doesn't throw an error either. That's strange

I still can't believe that this isn't automatically included in JS.

Useful, thanks!

I would be worth to have a replaceAll that makes use of replaceAt but with index update like (without RegExp of course)

text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.\nLorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.\nLorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."

replaceAll([{
		text: "Lorem",
		rep: "A",
		index: idx1
	},
	{
		text: "ipsum",
		rep: "B",
		index: idx2
	},
	{
		text: "eiusmod"
		rep: "C",
		index: idx3
	}
])

A B dolor sit amet, consectetur adipiscing elit, sed do C tempor incididunt ut labore et dolore magna aliqua.\nA B dolor sit amet, consectetur adipiscing elit, sed do C tempor incididunt ut labore et dolore magna aliqua.\nA B dolor sit amet, consectetur adipiscing elit, sed do C tempor incididunt ut labore et dolore magna aliqua
