Example 1: convert string to array js
// our string
let string = 'ABCDEFG';
// splits every letter in string into an item in our array
let newArray = string.split('');
console.log(newArray); // OUTPUTS: [ "A", "B", "C", "D", "E", "F", "G" ]
Example 2: string split javascript
var myString = "An,array,in,a,string,separated,by,a,comma";
var myArray = myString.split(",");
/*
*
* myArray :
* ['An', 'array', 'in', 'a', 'string', 'separated', 'by', 'a', 'comma']
*
*/
Example 3: string to array javascript
const str = 'Hello!';
console.log(Array.from(str)); // ["H", "e", "l", "l", "o", "!"]
Example 4: js string to array
var myString = 'no,u';
var MyArray = myString.split(',');//splits the text up in chunks
Example 5: convert a string to array in javascript
// Designed by shola for shola
str = 'How are you doing today?';
console.log(str.split(" "));
//try console.log(str.split("")); with no space in the split function
//try console.log(str.split(",")); with a comma in the split function
Example 6: convert string to array js
// créer une instance d'Array à partir de l'objet arguments qui est semblable à un tableau
function f() {
return Array.from(arguments);
}
f(1, 2, 3);
// [1, 2, 3]
// Ça fonctionne avec tous les objets itérables...
// Set
const s = new Set(["toto", "truc", "truc", "bidule"]);
Array.from(s);
// ["toto", "truc", "bidule"]
// Map
const m = new Map([[1, 2], [2, 4], [4, 8]]);
Array.from(m);
// [[1, 2], [2, 4], [4, 8]]
const mapper = new Map([["1", "a"], ["2", "b"]]);
Array.from(mapper.values());
// ["a", "b"]
Array.from(mapper.keys());
// ["1", "2"]
// String
Array.from("toto");
// ["t", "o", "t", "o"]
// En utilisant une fonction fléchée pour remplacer map
// et manipuler des éléments
Array.from([1, 2, 3], x => x + x);
// [2, 4, 6]
// Pour générer une séquence de nombres
Array.from({length: 5}, (v, k) => k);
// [0, 1, 2, 3, 4]
