    Minus 7

    How many times can you subtract 7 from a given number?

    Examples

    numMinusSeven(1000) === 143;
numMinusSeven(100) === 15;
numMinusSeven(10) === 2;
    Code 
    function numMinusSeven(num) {
    return Math.ceil(num / 7)
}
    Test Cases 
    const chai = require("chai");
const assert = chai.assert;

chai.config.truncateThreshold = 0;
const Test = require("@codewars/test-compat");

describe("Minus 7 test cases", function() {
  it("should test for 1000", function() {
      Test.assertEquals(numMinusSeven(1000), 143);
    });
  it("should test for 100", function() {
    Test.assertEquals(numMinusSeven(100), 15);
  });
  it("should test for 10", function() {
    Test.assertEquals(numMinusSeven(10), 2);
  });
