Let’s say, we have two strings that contains characters in no specific order. We are required to write a function that takes in these two strings and returns a modified version of the second string in which all the characters that were present in the first string are omitted.
Following are our strings −
const first = "hello world"; const second = "hey there";
Following is our function to remove all characters of first string from second −
const removeAll = (first, second) => { const newArr = second.split("").filter(el => { return !first.includes(el); }); return newArr.join(""); };
Let's write the code for this function −
Example
const first = "hello world"; const second = "hey there"; const removeAll = (first, second) => { const newArr = second.split("").filter(el => { return !first.includes(el); }); return newArr.join(""); }; console.log(removeAll(first, second));
Output
The output in the console will be −
