尝试使用 JavaScript 解决问题

Question

I am facing a problem with this issue

this is the question

This is my solution

 let whigt = { A: 1, B: 2, C: 3, D: 1, E: 2, F: 3, G: 1, H: 2, I: 3, J: 1, K: 2, L: 3, M: 1, N: 2, O: 3, P: 1, Q: 2, R: 3, S: 4, T: 1, U: 2, V: 3, W: 1, X: 2, Y: 3, Z: 4 } let charwhigt = 0; function presses(phrase) { let arraychar = phrase.toUpperCase().split(""); arraychar.map((el) => { console.log(whigt.el) }) } presses("omar")

I'm trying to link the object key to the letter, but when I print the object's value, it gives me the output NAN

What is my mistake did and what is the solution to make the solution right؟؟

Answer 1

Your code try to search el into whigt instead use [el] will search value of el

 let whigt = { A: 1, B: 2, C: 3, D: 1, E: 2, F: 3, G: 1, H: 2, I: 3, J: 1, K: 2, L: 3, M: 1, N: 2, O: 3, P: 1, Q: 2, R: 3, S: 4, T: 1, U: 2, V: 3, W: 1, X: 2, Y: 3, Z: 4 } let charwhigt = 0; function presses(phrase) { let arraychar = phrase.toUpperCase().split(""); arraychar.forEach((el) => { console.log(whigt[el]); }); } presses("omar");

PS: i prefer use forEach for loop array, see the differente here
