range javascript
[...Array(5).keys()];
=> [0, 1, 2, 3, 4]range in javascript
// while ES6 does not have any similar methods built-in
// the same basic functionality can be implemented by:
[...Array(5).keys()];
=> [0, 1, 2, 3, 4]
String.fromCharCode(...[...Array('D'.charCodeAt(0) - 'A'.charCodeAt(0) + 1).keys()].map(i => i + 'A'.charCodeAt(0)));
=> "ABCD"
// OR //
function range(size, startAt = 0) {
return [...Array(size).keys()].map(i => i + startAt);
}
function characterRange(startChar, endChar) {
return String.fromCharCode(...range(endChar.charCodeAt(0) -
startChar.charCodeAt(0), startChar.charCodeAt(0)))
