Quick fix for no-implicit-any errors to add explicit type annotation (#14786) * Infer from usage quick fix * Change full function singature * Add property/element access support * Fix a few issues * Some cleanup * Expose getArrayType and getPromiseType * Switch to collecting all usage before infering * Infer array and promise type arguments * Handel enums in binary operators * consolidate usage of addCandidateTypes * Handel rest paramters * Properly handel `+=` and `+` inference for numbers and strings * Add print quickfixes debug helper * Add rest param tests * Add optional paramter tests * Handel set accessors * Support getters * Support no implicit any error for variable at use site * Support properties * Only offer quick fix if an infered type other than any is available * Rename functions * Move to a separate namespace * Check cancellation token * Cleanup * Check for accesibile symbols where serializing types * Remove JS support * Reorganize functions * Mark APIs as internal * Fix lint errors * Removed conflict markers. * Update 'createSymbol' to use '__String'. * Fixed most problems relating to '__String' and 'includeJsDocComments' in the fix itself. * Addressed most API changes. * Make all helpers internal * Use a diffrent writer and not the built-in single line write * Infer types for all parameters in a parameter list instead of one at a time * Accept baselines * Code review commments * Respond to code review comments 2017-10-12 19:14:58 +02:00			`/// <reference path='fourslash.ts' />`

When --noUnusedLocals/--noUnusedParameters is disabled, add suggestions instead of errors (#22361) * When --noUnusedLocals/--noUnusedParameters is disabled, add suggestions instead of errors * Improve performance: do not add unused suggestion diagnostics unless asking for a suggestion * Add "unused" flag to diagnostics * Code review * reportsUnused -> reportsUnnecessary * Fix test 2018-04-05 21:33:00 +02:00			`//// a;`
