our goal here is to build, piece by piece, to a formula that will accept multiple points.
after this, the goal will be to define the visible area of the graph based on the min/max in the parameters.
function drawGraph(position) {
const width = 5;
const height = 5;
const arr = [];
for (let i = 0; i < height; i++) {
arr[i] = [];
};
arr.forEach((row, idx) => {
for (let i = 0; i < width; i++) {
row.push(" ");
}
(idx < width -1) ?
row[0] = "|" :
row[0] = "+";
})
let count = +1;
while (count < width) {
arr[width - 1][count] = "-";
count++;
}
arr[height - position.y - 1][position.x] = "*";
return arr;

});our first test of icodethis Kumite for pro members.
given a string (str), you should begin by removing the symbols.
Example:
"y&%ou sho!!!uld! no@t e@at yell==ow sn**ow" =>
"you should not eat yellow snow"
function removeSymbols(str) {
const regEx = /[&%!@=\*£]/g;
const newStr = str.replaceAll(regEx, "");
