The JavaScript Set entries() method gives an object of Set iterator that contains an array of [value, value] for each element. As there is no concept of key in set that’s why value and key are same.
Note: Iterator object maintains the insertion order.
Syntax:
setObj.entries()
Return:
A iterator object that contains an array of [value, value] for each element in the specified Set.
Example:
<!DOCTYPE html> <html> <body> <script> var jewels = new Set(); jewels.add("DIAMOND").add("GOLD").add("PLATINUM").add("SILVER"); var gems= jewels.entries(); for (let i of gems) { document.write(i+"<br>"); } </script> </body> </html> |
Output:
DIAMOND,DIAMOND GOLD,GOLD PLATINUM,PLATINUM SILVER,SILVER |
