babel: Choose a set of presets for output formatting.

babel

$ babel ${path-to-input_file} --presets ${presets}

try on your machine

This command is using Babel, a popular JavaScript compiler, to process an input file located at the specified path. Babel allows developers to write code using the latest JavaScript features and syntax that may not be supported by all browsers or environments, and then compiles it into a backward compatible version that can be executed on any target platform.

${path-to-input_file} is a placeholder that should be replaced with the actual path to the input file you want to process.

--presets ${presets} is an option that specifies which set of Babel presets to use during the compilation process. Presets in Babel are a predefined group of plugins and configurations that enable specific language features or transformations. ${presets} is another placeholder that should be replaced with the desired preset or a comma-separated list of multiple presets.

For example, the command could be written as:

babel ./src/index.js --presets react,env

This would compile the input file located at ./src/index.js using the Babel presets for React and the latest ECMAScript features provided by the env preset.
