// To get the last "Word" of a string use the following code :

let string = 'I am a string'

let splitString = string.split(' ')

let lastWord = splitString[splitString.length - 1]
console.log(lastWord)

/*
Explanation : Here we just split the string whenever there is a space and we get an array. After that we simply use .length -1 to get the last word contained in that array that is also the last word of the string.
