Fix ESLint "const should be let"
Learn the exact difference between const and let variables in Javascript block codes to solve ESLint syntax warnings.
Direct ES6 Syntax Override
Change the variable assignment instruction fromconst to let to permit subsequent mutations and solve ESLint linting warnings.
# Understanding the Lint Error
The no-const-assign rule prevents developers from mutating variables instantiated under constant bounds:
``javascript
// Reassigning constant strings triggers ESLint warning
const username = 'John';
username = 'Doe';
`
# Step 1: Re-instantiate Under Let Bounds
Convert variables bound to undergo later reassignments into standard flex structures:
`javascript
// Let assignments handle reassignment gracefully
let username = 'John';
username = 'Doe';
`
# Step 2: Keep Objects Constant
If variables hold complex objects or lists, remember that reassigning internal properties is allowed:
`javascript
// Modifying properties of constants is legal
const state = { active: false };
state.active = true; // Does NOT trigger ESLint errors
``
