var or const in javascript
// var declares a variable, meaning its value will vary. // const declares a constant, meaning its value will remain // consistant and not change. // If your variable changes throughout the program or website, // declare it using a var statement. // Otherwise, if its value does not change, declare it using // a const statement. const myConst='A const does not change.'; var myVar='A var does change.'; var myVar=2;
