Print numbers 1 to 100

Print numbers 1 to 100 JavaScript coding practice with problem statement, input, output, step-by-step logic, solution, explanation, complexity, and variations.

Overview & Purpose

Print numbers 1 to 100 is a coding-round problem designed to improve problem solving, loops, conditions, functions, and edge-case thinking.

Topic Definition

Problem statement: write a JavaScript function for print numbers 1 to 100 and verify it with sample input and output.

Why It Matters

Coding practice builds the ability to convert a plain-English requirement into working logic under interview time limits.

Syntax Guide

javascript
function solve(input) {
  return input;
}

console.log(solve("Print numbers 1 to 100"));
Reference API Specifications
Parameters:
  • input: sample value to process
  • return value: solved output
  • variation: change input size or edge cases
Return Value:

Returns the computed answer for the given problem input.

Syntax Explanation: Break the problem into input, expected output, step-by-step logic, code, complexity, and variation. This is the format interviewers expect.

Runnable Code Examples

Example 1: Problem statement and sample

Solve: Print numbers 1 to 100.

javascript
function solve(input) {
  return input;
}

console.log(solve("Print numbers 1 to 100"));
expected console output
Print numbers 1 to 100

Breakdown: This starter shape shows where the final problem logic belongs.

Example 2: Step-by-step logic

Use comments to dry-run before writing code.

javascript
// 1. Read input
// 2. Initialize result
// 3. Loop or transform
// 4. Return result
expected console output
A clear algorithm plan

Breakdown: A plan prevents random trial-and-error coding.

Example 3: Complexity note

State time and space complexity.

javascript
// Time complexity: O(n) for one pass
// Space complexity: O(1) if no extra collection is created
expected console output
Complexity explained

Breakdown: Complexity discussion is expected in coding rounds.

Real-world Use Cases

  • 1Technical interview coding rounds.
  • 2Improving loops, arrays, strings, and object manipulation.
  • 3Preparing for output-based JavaScript questions.
  • 4Learning dry-run and debugging habits.
  • 5Building confidence before larger projects.

Avoid Common Mistakes

Mistake 1

Not writing sample input and output first.

Mistake 2

Ignoring edge cases like empty strings or single-item arrays.

Mistake 3

Changing the input accidentally when a pure function is expected.

Mistake 4

Using built-in methods when the interviewer asks for manual logic.

Mistake 5

Forgetting to explain time and space complexity.

Pro Tips & Practices

Practice 1

Clarify constraints before coding.

Practice 2

Write small helper functions when logic repeats.

Practice 3

Dry-run with at least two inputs.

Practice 4

Return values instead of only logging.

Practice 5

Mention complexity after the solution works.

Pro Tip 1

Narrate your plan before typing in interviews.

Pro Tip 2

Use meaningful variable names like frequencyMap or result.

Pro Tip 3

Test empty, normal, and large inputs.

Pro Tip 4

Avoid clever one-liners unless asked.

Pro Tip 5

Compare manual and built-in solutions after finishing.
