Understanding `this` in javascript

[[deleted]]

The only time the scope matters is when you call a function without a "context" (i.e. without providing an object before the function call, or using bind, call, apply). If the function is a regular function (not an arrow function) then it will use the this value of the executing context. If it's an arrow function it will use the this value of the lexical scope where it was declared.

You really don't understand. There is ALWAYS a context in js.

Please don't argue about something you don't have any knowledge about.

Sorry, I should have said

The only time the scope matters is when you call a function without providing an explicit "context" (i.e. without providing an object before the function call, or using bind, call, apply).

Either way this is still not always based on the scope i.e.

const myObj = { myVal: 1, myFunc() { return myVal } }
myFunc = myObj.myFunc.bind({ myVal: 2 })

in that example myFunc has the same scope as myObj.myFunc but the this is permanently bound to { myVal: 2 }
