HTML canvas lineJoin Property

The HTML canvas lineJoin property is used to set or return the type of corner created, when two lines meet, by using the lineJoin property. The type of join can have one of three styles: bevel, round, or miter. However, the join style has generally miter style. Syntax:

context.lineJoin = "bevel|round|miter";

Property Values:

miter: It is the default style. This value is used to design a sharp corner.
bevel: This design is used to create beveled corner.
round: This design is used to create rounded corner.

Example 1: This example illustrates the miter linejoin property.
