How to get odd and even position characters from a string?
We have to write a function that removes every second character (starting from the very first
character) from a string and appends all of those removed characters at the end in JavaScript.
For example −
If the string is "This is a test!"
Then it should become "hsi etTi sats!"
Therefore, let’s write the code for this function −
Example
const string = 'This is a test!';
const separateString = (str) => {
const { first, second } = [...str].reduce((acc, val, ind) => {
const { first, second } = acc;
return {
first: ind % 2 === 1 ? first+val : first,
second: ind % 2 === 0 ? second+val : second
};
}, {
first: '',
second: ''
})
return first+second;
};
console.log(separateString(string));Output
The output in the console will be −
hsi etTi sats!
