Here my ternary :
mode === 'edition' ? (this.editionMode = true, this.creationMode = false) : (this.creationMode = true, this.editionMode = false)
I think it's redundant, can i write this ternary in a better way ? Thanks !


this.editionMode = mode === 'edition';
this.creationMode = !this.editionMode;

In javascript if you have this by example:
const a = document.createElement("img");
a.src = "test.png";
document.getElementById("parent").appendChild(a);
Will this give true? -> document.getElementById("parent").hasChildNodes();

const a = document.createElement("img");
a.src = "https://www.gravatar.com/avatar/b4185aac47f6262b40dc8f11535a32c0?s=48&d=identicon&r=PG";
document.getElementById("parent").appendChild(a);
console.log(document.getElementById("parent").hasChildNodes());
<div id="parent"></div>

let valor = value.replace("'","")
valor=valor.replace('"',"")
//or
name=value.replace("'","").replace('"',"")

A better option might be to use a single .replace instead, and use a regular expression to match either ' or ":
const valor = value.replace(/['"]/g, '');

I need to check if the value of the input consists of numbers(0-9). Thanks for helping.

You can use Regular Expressions:
var result = /^[\d]+$/.test(yourInput);

Try to use isNumeric like this:
if($.isNumeric( input ) && parseInt(input)<10 && parseInt(input)>=0){
...
}

how would I check for string
<something> in var string = "some chars <something> somechars"

You can use String.match():
var res = string.match(/<something>/g); // ["<something>"]
If there is no match, the value of res will be null. See example on JSFiddle.
