How to create a two dimensional (2D) array dynamically with random rows and cols in TypeScript

Answer 1

const rows = Math.floor(Math.random() * 9) + 1;
const cols = Math.floor(Math.random() * 7);
  
let count = 1;
let array = [];
 
for (let i = 0; i < rows; i++) {
    let data = [];
    for (let j = 0; j < cols; j++) {
        data.push("value" + count);
        count++;
    }
    array.push(data);
}
 
console.log(array);
    
    
      
      
/*
run:
      
[["value1", "value2", "value3", "value4"], 
 ["value5", "value6", "value7", "value8"], 
 ["value9", "value10", "value11", "value12"], 
 ["value13", "value14", "value15", "value16"], 
 ["value17", "value18", "value19", "value20"], 
 ["value21", "value22", "value23", "value24"]] 
      
*/
