js randomly selects colors from 10 colors to achieve different colors each time_javascript skills

Yesterday I was doing js to randomly select colors from 10 colors, and every time I took out a different color, I thought a lot, and finally implemented it as follows:

Copy code The code is as follows:

var colorList = ["#FFFF99","#B5FF91","#94DBFF","#FFBAFF","#FFBD9D", "#C7A3ED","#CC9898","#8AC007","#CCC007","#FFAD5C"];
for(var i=0;ivar bgColor = getColorByRandom(colorList);
}
function getColorByRandom(colorList){
var colorIndex = Math.floor(Math.random()*colorList.length);
var color = colorList[colorIndex] ;
colorList.splice(colorIndex,1);
return color;
}

In this way, the color taken out every time is random and different.
