AngularJS Developer Interview Question:

Please explain what is Angular Expression? Explain what is key difference between angular expressions and JavaScript expressions?

Submitted by: Muhammad

Like JavaScript, Angular expressions are code snippets that are usually placed in binding such as {{ expression }}

The key difference between the JavaScript expressions and Angular expressions

☛ Context : In Angular, the expressions are evaluated against a scope object, while the Javascript expressions are evaluated against the global window
☛ Forgiving: In Angular expression evaluation is forgiving to null and undefined, while in Javascript undefined properties generates TypeError or ReferenceError
☛ No Control Flow Statements: Loops, conditionals or exceptions cannot be used in an angular expression
☛ Filters: To format data before displaying it you can use filters
