Not sure if I’m doing an error in the code, but when I try to find the index of the letter z that is in the array I’ve split I will get this error:
TypeError: string "z" is not a function
at Array.findIndex (<anonymous>)
Here is the code:
const chars: string = "abcdefghilmnopqrstuwxyz0123456789@-_+*(),.#";
let outputMatrix: Array<string> = [];
let outputWord: string = "";
// Split input matrix function
const splitMatrix = async (inputMatrix: string) => {
let splitted = inputMatrix.split('');
let uppercaseChars = splitted.findIndex('z');
console.log(uppercaseChars)
console.log(splitted)
return splitted;
}
// Generating random word
const createRandomString = (splittedChars: Array<string>, length?: number) => {
const defaultLength: number = 12;
const min: number = 0;
const max: number = splittedChars.length;
let num: number;
if (length) {
for(let i: number = 0; i < length; i++) {
num = Math.floor(Math.random() * (max - min) + min);
outputWord += splittedChars[num];
}
return outputWord;
} else {
for(let i: number = 0; i < defaultLength; i++) {
num = Math.floor(Math.random() * (max - min) + min);
outputWord += splittedChars[num];
}
}
console.log('Generated password', outputWord);
}
const main = () => {
splitMatrix(chars)
.then( (outputMatrix) => {
createRandomString(outputMatrix);
});
}
main();
What I want to do is to get the index of the z letter and after this extract all the elements that are before the letter including the letter to uppercase them.
