I have one array as below
var arr = ["john doe first", "robert way", "jason doe", "alex"];
Now i want to convert this array like below.
var result = ["john", "doe", "first", "robert", "way", "jason",
"doe", "alex"];
Quick explanation is i need convert each array element of string into array and reset it into the array. Array index is not important. I tried arr.split(" ") even arr.toString() and then arr.split(" "). I don't know what i'm missing here.
You can simply use Array#join and String#split :
var arr = ["john doe first", "robert way", "jason doe", "alex"];
console.log(arr.join(' ').split(' '));If your Strings have more than one space separating your words :
Add .filter(Boolean) to remove the empty Strings
var arr = ["john doe first", "robert way", "jason doe", "alex"];
console.log(arr.join(' ').split(' ').filter(Boolean));
Use reduce, concat and split
arr.reduce( (a , c) => a.concat(c.split(/\s+/)), [])
Demo
var output = ["john doe first", "robert way", "jason doe", "alex"].reduce( (a , c) => a.concat(c.split(/\s+/)), []);
console.log( output );You could use concat method with spread syntax ... to add to a new array and map and split methods to split each element on white space.
var arr = ["john doe first", "robert way", "jason doe", "alex"];
var result = [].concat(...arr.map(e => e.split(' ')));
console.log(result)You can use spread operator in a forEach loop:
var arr = ["john doe first", "robert way", "jason doe", "alex"];
var res = [];
arr.forEach((item)=>{
var tempArray = item.split(' ');
res.push(...tempArray);
});
console.log(res);
var arr = ["john doe first", "robert way", "jason doe", "alex"];
function formatArray(array){
var newArr=[];
array.forEach(function(item){
item.split(' ').forEach(function(itemSplitted){
newArr.push(itemSplitted);
});
});
return newArr;
}
console.log(formatArray(arr));Use this:
var arr = ["john doe first", "robert way", "jason doe", "alex"];
var finalArray = []
for(var i = 0; i < arr.length; i ++) {
arr[i].split(' ').forEach(function(item) {finalArray.push(item);});
}
console.log(finalArray)
var arr = ["john dvoe first", "robert way", "jason doe", "alex"];
var arr2= arr.map(function(item){return item.split(" ")});
var result=[].concat.apply([],arr2);
const arr = ["john doe first", "robert way", "jason doe", "alex"];
let result = []
arr.map((e) => {
result = result.concat(e.split(/[ ,]+/))
})
console.log(result);
