When working with the TypeScript example above, I encountered 2 errors. The first error was related to `i` in the second console.log due to the use of the 'let' keyword. The second error was regarding 'test' in the first line, stating it as a Duplication Function implementation. Any suggestions or insights on how to address these issues?
function test(){
for(let i=0; i<5; i++){
console.log(i);
}
console.log("finally:" + i);
}
test();
The issue in the code is as follows:
console.log("finally:" + i);
That's all.
So, how can we resolve this issue?
function test(){
let i = 0;
for(; i<5; i++){
console.log(i);
}
console.log("finally:" + i);
}
test();
What caused the problem?
The problem arose because let has block-level scope.
You should not try to access it outside of the block where it was declared.
Edit: Avoid reinitializing the value of i.
