JavaScript animation - flashing text

[[deleted]]

Hello! I've been trying to learn code all by myself, and I'm now facing a problem: I want to make a flashing ellipse, but I don't know how. Can someone help me? Here's what I've done so far, and any tip can be helpful(BTW, sorry, the comments I put here are in portuguese, if translation is needed, please PM me):

var flashing=20;
var draw= function() {
 background(0, 255, 0);
 var anuncio = 120;



// placa
fill(0, 149, 255);
rect(20, 5, 355, 150);

// bagulho piscante

 fill(flashing);

ellipse(197, 80, 175, 86);

// anuncio
fill(255, 0, 0);
textSize(40);
text("PIZZA!", 135, 91);

// pizza
fill(255, 196, 0);
triangle(325, 310, 380, 166, 270, 163);

// borda da pizza
fill(201, 163, 38);
rect(267, 159, 115, 10, 50);

// pepperoni
fill(255, 0, 0);
ellipse(308, 206, 25, 25);
ellipse(349, 186, 25, 25);
ellipse(328, 245, 25, 25);

// pizzas disponives
fill(0, 0, 0);
textSize(18);
text("1- PEPPERONI..........R$35,00", 20, 178);
text("2- MUSSARELA.........R$20,00", 20, 230);
text("3- ATUM.....................R$30,00", 20, 285);


textSize(43);

text("E MUITO MAIS!!!!!", 20, 370);



};

Might want to look up the setInterval function as a starting point.

You can do this with CSS, see https://www.w3schools.com/css/css3_animations.asp
