CanvasRenderingContext2D: lineTo() method
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
TheCanvasRenderingContext2D methodlineTo(), part of the Canvas 2D API, adds a straight lineto the current sub-path by connecting the sub-path's last point to the specified(x, y) coordinates.
Like other methods that modify the current path, this method does not directly renderanything. To draw the path onto a canvas, you can use thefill() orstroke() methods.

Examples
>Drawing a straight line
This example draws a straight line using thelineTo() method.
HTML
<canvas></canvas>JavaScript
The line begins at (30, 50) and ends at (150, 100).
const canvas = document.getElementById("canvas");const ctx = canvas.getContext("2d");ctx.beginPath(); // Start a new pathctx.moveTo(30, 50); // Move the pen to (30, 50)ctx.lineTo(150, 100); // Draw a line to (150, 100)ctx.stroke(); // Render the pathResult
Drawing connected lines
Each call oflineTo() (and similar methods) automatically adds to thecurrent sub-path, which means that all the lines will all be stroked or filled together.This example draws a letter 'M' with a single contiguous line.
HTML
<canvas></canvas>JavaScript
const canvas = document.getElementById("canvas");const ctx = canvas.getContext("2d");ctx.moveTo(90, 130);ctx.lineTo(95, 25);ctx.lineTo(150, 80);ctx.lineTo(205, 25);ctx.lineTo(210, 130);ctx.lineWidth = 15;ctx.stroke();Result
