convert string to array js

1// our string
2let string = 'ABCDEFG';

4// splits every letter in string into an item in our array
5let newArray = string.split('');

7console.log(newArray); // OUTPUTS: [ "A", "B", "C", "D", "E", "F", "G" ]

1const str = 'Hello!';

3console.log(Array.from(str)); //  ["H", "e", "l", "l", "o", "!"]

1var myString = 'no,u';
2var MyArray = myString.split(',');//splits the text up in chunks

3str = 'How are you doing today?';
4console.log(str.split(" "));

6//try console.log(str.split(""));  with no space in the split function
7//try console.log(str.split(","));  with a comma in the split function

1// créer une instance d'Array à partir de l'objet arguments qui est semblable à un tableau
2function f() {

34// En utilisant une fonction fléchée pour remplacer map
35// et manipuler des éléments
36Array.from([1, 2, 3], x => x + x);
