Example:
var someArray = ["My Name is", "My is Name", "Name my is", "is Name my"]
I want to print the last element of each string, so:
output: is, Name, is, my
I have no idea where I should start. My first thought was to split the array and print the last index, but I didn't succeed
Use Array.map
var someArray = ["My Name is", "My is Name", "Name my is", "is Name my"];
let result = someArray.map(v => {
let temp = v.split(" ");
return temp[temp.length-1];
})
console.log(result);You can use a regular expression to match the last word.
var someArray = ["My Name is", "My is Name", "Name my is", "is Name my"]
var result = someArray.map(item => item.match(/\w+$/)[0]);
console.log(result);
var someArray = ["My Name is", "My is Name", "Name my is", "is Name my"];
var lastElements = "";
someArray.forEach(str => {
splitStr = str.split(" ");
lastElements += splitStr[splitStr.length - 1] + ", ";
});
console.log('output: ', lastElements);
//Outputs output: is, Name, is, my,
Another simple approach:
const someArray = ["My Name is", "My is Name", "Name my is", "is Name my"]
const output = someArray.map(str => str.split(' ').pop());
console.log(output);
