What is the arrow in functions?

Arrow functions are a new way to write anonymous function expressions , and are similar to lambda functions in some other programming languages, such as Python. Arrow functions differ from traditional functions in a number of ways, including the way their scope is determined and how their syntax is expressed.

Draw arrows with Path objects easily. Paths can be composited to add arrows to any curve and draw all at once. The arrow is drawn using the direction of the tangent to the curve at the end of the curve .

This arrow syntax is a way to define a function that executes the expression to its right and returns its value . By using fat arrow => the curly brackets needs to be removed. Otherwise, the code editor will show you an error.17 Ara 2020
