In an object's prototype function, this refers to the object that is being called. In other scenarios, this might refer to different things (e.g execution context, or global/window if it's not set, or null if strict mode is also active). You can also specify the context when calling a function by using Function.prototype.call/apply/bind.
I assume 'this' refers to a specific array that the numberOfOccurence method is applied to. However, can someone explain how 'this' works in this code in more detail? Thanks!
In JavaScrpt,
thisis the execution context:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/this
