The substrChartAt Kumite is a simple JavaScript function that allows you to remove a character from a string at a specific index. It's particularly useful when you need to modify strings by removing a character at a certain position.
Usage
The substrChartAt function takes two parameters:
str: The input string from which you want to remove a character.
index: The index at which the character should be removed. It's a 0-based index, so 0 refers to the first character, 1 to the second, and so on.
Example:
Example:
const modifiedString = substrChartAt("example", 3);
// The resulting string will be "exmple"
This utility provides a convenient way to manipulate strings and create modified versions of them in your JavaScript katas.
const substrChartAt = (str, index) => {
return str.slice(0, index) + str.slice(++index);
};// Since Node 10, we're using Mocha.
// You can use `chai` for assertions.
const chai = require("chai");
const assert = chai.assert;
// Uncomment the following line to disable truncating failure messages for deep equals, do:
// chai.config.truncateThreshold = 0;
// Since Node 12, we no longer include assertions from our deprecated custom test framework by default.
// Uncomment the following to use the old assertions:
const Test = require("@codewars/test-compat");

});
