Now that we know its syntax and its parameters, let’s see this method in action. thisArg: a value to use as the context ( this) of the mapFn function.mapFn: a function to call on every element contained.arrayLike: an array-like or an iterable object.The syntax of om() is shown below: Array. This method can be used to solve an old problem with array-like objects that most developers solve using this code: // typically arrayLike is arguments var arr =.
It creates a new Array instance from an array-like or an iterable object. The first method I want to mention is om().
