Question

How to divide a string into N equal parts with TypeScript

Answer 1

function DivideStringIntoEqualParts(str : string, parts : number) {
    const length : number = str.length;

    if (length % parts != 0) {
        console.log("No equal parts");
        return null;
    }
    
    let j : number = 0;
    const part_size : number = length / parts;
    let parts_arr : string[] = Array(parts).fill(null);
        
    for (let i : number = 0; i < length; i = i + part_size) {
        parts_arr[j] = str.substring(i, i + part_size);
        j++;
    }
    return parts_arr;
}
        

const str : string = "typescript c++ c java python";
const parts : number = 4;

const parts_arr : any = DivideStringIntoEqualParts(str, parts);
  
if (parts_arr != null) {      
    for (let i = 0; i < parts_arr.length; i++) {
        console.log(parts_arr[i]);
    }
}

    return parts_arr;
