Here is an array example I have:
var array= ['business>management', 'News>Entertainment News', 'business>Entrepreneurship'];
I want this result:
['business', 'management', 'News', 'Entertainment News', 'Entrepreneurship']
It means, separate from this '>' No duplicate
This is an example of where I'm at but it just removes the arrow '>' jsfiddle
You can use reduce() and Set combination for example. Read from the docs:
The
Setobject lets you store unique values of any type, whether primitive values or object references.The
reduce()method executes a reducer function (that you provide) on each element of the array, resulting in single output value.
Please see a possible working solution.
const array = ['business>management', 'News>Entertainment News', 'business>Entrepreneurship'];
const result = array.reduce((a,c) => {
c.split('>').forEach(e => a.add(e));
return a;
}, new Set());
const unique = Array.from(result);
console.log(unique);I hope that helps!
try this one -
const array = ['business>management', 'News>Entertainment News', 'business>Entrepreneurship'];
let newArray = []
array.map((item)=>{
let newData = item.split(">").map((itemIn)=>{
newArray.push(itemIn)
return item
})
return newData
})
console.log(newArray)
Simplified
let array = ['business>management', 'News>Entertainment News', 'business>Entrepreneurship'];
let separated = array.map((item, ii) => {
return item.split(">")
}).reduce((a, b) => a.concat(b)).filter((value, index, self) => {
return self.indexOf(value) === index;
});
console.log(separated)
You could use .flatMap() with .split() to create an array of strings split by '>'. Then you can put these results into a Set to remove duplicates, and then back into an array using the spread syntax (...).
const array = ['business>management', 'News>Entertainment News', 'business>Entrepreneurship'];
const result = [...new Set(array.flatMap(str => str.split('>')))];
console.log(result);If you can't use .flatMap() due to compatibility concerns, you can always use .map() and then flatten the array afterwards using .concat() which has much better browser comptability:
const arr = ['business>management', 'News>Entertainment News', 'business>Entrepreneurship'];
const result = [...new Set([].concat(...arr.map(s => s.split('>'))))];
console.log(result);
