The strokeWeight() function in p5.js is used to set the width of the stroke used for lines, points and the border around shapes. The stroke weight is set by using pixels.
Syntax:
strokeWeight(weight)
Parameters: This function accepts a single parameter weight which stores the weight (in pixels) of the stroke. The below programs illustrate the strokeWeight() function in p5.js:
Example 1: This example uses strokeWeight() function to set the width of the stroke.
function setup() {
// Create Canvas of given size
createCanvas(380, 170);
} function draw() {
// Set the background color
background(220);
// Set the stroke width
strokeWeight(20);
// Set the filled color
fill( 'green' );
// Draw the circle
circle(60, 60, 34);
// Set the text size
textSize(20);
// Set the text to print
text( "GeeksForGeeks" , 120, 70);

Example 2: This example uses strokeWeight() function to set the width of the stroke.
function setup() {
// Create Canvas of given size
createCanvas(380, 170);
} function draw() {
// Set the background color
background(220);
// Set the stroke color
stroke( 'orange' );
// Set the stroke width to 10
strokeWeight(10); // Orange
// Draw a line
line(20, 70, 80, 70);
// Set the stroke color
stroke( 'white' );
// Set the stroke width to 8
strokeWeight(8); // White
// Draw a line
line(20, 90, 80, 90);
// Set stroke color
stroke( 'green' );
// Set the stroke width to 6
strokeWeight(6); // Green
// Draw a line
line(20, 110, 80, 110);
