Task 143

What's wrong?
`export const extractNumber = (s) => { const quitar = /-?[\d.]+/g;

return s.match(quitar);
}`

Coderslang_Master

export const extractNumber = (s) => {
  const quitar = /-?[\d.]+/g;
  return s.match(quitar);
}

We haven't covered regular expression by lecture 14, so try to solve this task using a plain for loop.

Coderslang_Master

akntov also check what your function returns. Now it's a boolean, but shouldn't it be a number?

Coderslang_Master I dón´t have idea.

akntov if you don't have an idea, then don't use regular expressions. Use a simple for loop.

Solving this problem without using code, which at the time of obtaining this problem has not yet been considered in the lectures.

export const extractNumber = (s) => { let r = ''; let arrayOfSymbols = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '.']; for (let i=0; i < s.length; i++) { if (arrayOfSymbols.includes(s[i])){ r = r + s[i]; }; } return Number(r); }
